Write an equation for the line that is parallel to the given line and passes through the given point.

y=3x+4;(6,8)
A. y=3x-10
B. y=3x+6
C. y=-3x+6
D. y=-1/3x-6

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
y=-3x+7
-2x+6y=3
A. Parallel
B. Perpendicular
C. Neither

1. B
2.A
Thank you for the help

To check #1

You say B which is y=3x+6
if x = 6
y = 3(6) + 6 = 18+6 = 24
NO!
See, you can check without asking me.

y = 18+b
y = 8
8 = 18+b
b = -10
so the RIGHT answer is
y = 3x -10
which is A

now
slope of first = -3
second is
6y = 2x + 3 , slope = +1/3
second slope = -1/first slope
so
PERPENDICULAR

You are welcome and good luck ! I hope your grandmother comes through all right.

1. Correct! The equation for the line that is parallel to y=3x+4 and passes through the point (6,8) is y=3x+6 (Option B).

2. Correct! The lines y=-3x+7 and -2x+6y=3 are perpendicular (Option B).

You're welcome! Let me know if there's anything else I can help with.

To find an equation for a line that is parallel to the given line, we need to consider that parallel lines have the same slope. The given line has a slope of 3 (from the equation y=3x+4). Now, let's use the point-slope form of a linear equation to find the equation for the line that passes through the given point (6,8).

The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope of the line. Plugging in the values, we get:

y - 8 = 3(x - 6)

Simplifying the equation, we have:

y - 8 = 3x - 18

Adding 8 to both sides, we have:

y = 3x - 10

Therefore, the equation for the line that is parallel to y=3x+4 and passes through (6,8) is y=3x-10.

So the correct answer is A. y=3x-10.

To determine whether the lines for each pair of equations are parallel, perpendicular, or neither, we need to compare their slopes. The slope-intercept form of an equation (y=mx+b) allows us to easily see the slope.

For the first pair of equations:
Given: y = -3x + 7
Comparing with y = mx + b, we find that the slope is -3.

For the second equation: -2x + 6y = 3
We need to rearrange the equation to slope-intercept form:
6y = 2x + 3
y = 2/6x + 3/6
y = 1/3x + 1/2

Comparing with y = mx + b, we find that the slope is 1/3.

Since the slopes are not the same (i.e. -3 and 1/3 are not equal), the lines for the pair of equations are neither parallel nor perpendicular.

So the correct answer is C. Neither.

Therefore, the correct answers are:
1. B. y=3x-10
2. C. Neither

Thank you for the help Damon, I'm sorry for not getting the answers right I just found out my grandma has cancer and have been staying with her at the hospital recently so I have been having a little trouble.Thank you for showing me how to get it step by step.
