I would love for someone to check my work on the seven problems that I did. I would be eternally grateful. I am going to list my problems and answers. Even if you only want to check one of them, that would be great.

1. Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4).
I got y=-3x+13
2. Write the equation of a line in point slope form that has a slope of -3/4 and passes through the point (4,5).
I got y=-3/4x+8
3. Write the equation of a line in slope intercept form that passes through the points (-2, 7) and (3, 12)
I got y=x+9
4. Write an equation of a line in slope intercept form that is parallel to y=3x+6 and passes through point (-10, 2.5).
I got y=3x+32.5
5. Write an equation of a line in slope intercept form that is perpendicular to y=-4x-2 and passes through the point (-16, -11).
I got y=1/4x-7
6. Write an equation of a line in slope intercept form that is parallel to the line x+4y=6 and passes through -8, 5).
I got y=x+28
7. Write an equation of a line in slope intercept form that is perpendicular to the line 2x-3y=12 and passes through the point (2, 6).
I got -1/2x-17

1. Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4).

I got y=-3x+13

Hey - you do not need me to check. Just put the point back in
what is y if x = 3 ????
y = -3 (3) + 13
y = -9 + 13 = -4
Right :)

HOWEVER it said "point slope form"

y - y1 = m(x - x1)

y - -4 = -3 (x - 3)
or in other words
y + 4 = -3 (x-3)

Arno the man, the myth, the legend.

Now number 4 asks for "slope intercept form"

y = m x + b

m = 3 yes same slope
2.5 = 3(-10) + b
2.5 = -30 + b
b = 32.5
so we agree

i got y= 4x + 19

Dude Arno you are a legend what you said it 100%, thank you so much.

To check your work, we need to verify if the given points satisfy the equations you provided. Let's go through each problem one by one:

1. Write an equation of a line in point-slope form that has a slope of -3 and passes through the point (3, -4).

The point-slope form of a linear equation is given by: y - y1 = m(x - x1), where (x1, y1) are the coordinates of a point on the line, and m is the slope.

Using the given slope (-3) and point (3, -4), we can substitute these values into the equation to see if it holds:
y - (-4) = -3(x - 3)
y + 4 = -3x + 9
y = -3x + 5

The correct equation is y = -3x + 5. Therefore, your answer for problem 1 is incorrect.

2. Write the equation of a line in point-slope form that has a slope of -3/4 and passes through the point (4, 5).

Using the same formula, we substitute the given slope (-3/4) and point (4, 5):
y - 5 = (-3/4)(x - 4)
y - 5 = (-3/4)x + 3
y = (-3/4)x + 8

The correct equation is y = (-3/4)x + 8. Your answer for problem 2 is correct.

3. Write the equation of a line in slope-intercept form that passes through the points (-2, 7) and (3, 12).

In slope-intercept form, the equation is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope (m) using the two points:
m = (y2 - y1) / (x2 - x1)
m = (12 - 7) / (3 - (-2))
m = 5 / 5
m = 1

Now that we have the slope, we can choose one of the points to find the y-intercept (b). Let's use (-2, 7):
7 = 1(-2) + b
7 = -2 + b
b = 9

The correct equation is y = x + 9. Your answer for problem 3 is correct.

I will continue with the remaining problems in subsequent responses.
