Hey i need help on my math hw i just don't get it lol please help me!
Here the questions
Which of the following equations has a graph that is parallel to the graph of
4x-2y=7?
A:-2y = 4x+2
B:7-4x=2y
C:4x+2y=2
D:-4x-2y=-7
E:2y=4x+7
Determine if the two lines 7x+5y=35 and y= -7 over 5x-1 are parallel, perpendicular, or neither.
Which of the following lines is not parallel to y=5x+2?
A:5y-x=1
B:5x-y=1
C:y-5x=4
D:10x-2y=1
PLEASE HELP ME I NEED THIS BY 4
Which of the following equations has a graph that is parallel to the graph of
4x-2y=7?----- m = +2
A:-2y = 4x+2-- m = -2
B:7-4x=2y -----m = -2
C:4x+2y=2 -----m = -2
D:-4x-2y=-7 ---m = -2
E:2y=4x+7 -----m = +2 Yes this one
7x+5y=35 and y= -7 over 5x-1
m = -7/5
and
y = -7/(5x-1) which is not a straight line at all. Typo?????
y=5x+2? --------m = 5
A:5y-x=1--------m = 1/5 not parallel
B:5x-y=1--------m = 5 yes parallel
C:y-5x=4 -------m = 5 yes parallel
D:10x-2y=1 -----m = 5 yes parallel

I HATE MATH
Sure, I'd be happy to help you with your math homework! Let's go through each question one by one.
1) To determine which equation has a graph that is parallel to the graph of 4x-2y=7, we need to find an equation with the same slope. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope. In 4x-2y=7, rearrange the equation to slope-intercept form to find:
-2y = -4x + 7
Divide both sides by -2 to isolate y:
y = 2x - 7
Now, let's compare this equation to the options provided:
A: -2y = 4x + 2
Rearranging to slope-intercept form: y = -2x - 1
B: 7-4x=2y
Rearranging to slope-intercept form: y = -2x + 3.5
C: 4x+2y=2
Rearranging to slope-intercept form: y = -2x + 1
D: -4x-2y=-7
Rearranging to slope-intercept form: y = -2x + 3.5
E: 2y=4x+7
Rearranging to slope-intercept form: y = 2x + 3.5
By comparing the slopes of each equation to the slope of the original equation, we can see that the graph parallel to 4x-2y=7 would be option D: -4x-2y=-7.
2) To determine if the two lines 7x+5y=35 and y= (-7/5)x-1 are parallel, perpendicular, or neither, we can look at the slopes of the two lines. The slope-intercept form y = mx + b, where m represents the slope.
For the line 7x+5y=35, rearrange the equation to slope-intercept form:
5y = -7x + 35
Divide both sides by 5 to isolate y:
y = -7/5x + 7
Now compare this equation's slope with the slope of the second equation y = (-7/5)x - 1.
Both lines have a slope of -7/5, which means they are parallel.
3) To determine which of the following lines is not parallel to y=5x+2, we need to compare the slopes of each equation.
The equation y=5x+2 is already in slope-intercept form, so we can easily identify the slope, which is 5.
Let's compare the slopes of the options provided:
A: 5y - x = 1
Rearranging to slope-intercept form: y = (1/5)x + 1/5
This line has a slope of 1/5, which is not equal to 5. Therefore, it is not parallel to y=5x+2. Option A is the correct answer.
B: 5x - y = 1
Rearranging to slope-intercept form: y = 5x - 1
This line has a slope of 5, which is parallel to y=5x+2.
C: y - 5x = 4
Rearranging to slope-intercept form: y = 5x + 4
This line has a slope of 5, which is parallel to y=5x+2.
D: 10x - 2y = 1
Rearranging to slope-intercept form: y = 5x - 1/2
This line has a slope of 5/2, which is not equal to 5. Therefore, it is not parallel to y=5x+2.
Therefore, the line not parallel to y=5x+2 is option A: 5y - x = 1.
I hope this helps! If you have any further questions, feel free to ask.
