Question

What is the equation of the line that is parallel to line y = -3x – 8 and passes

through the point (-2, 9)?
y= 1x + 29
y = -3x + 11
y = -3x + 3
y = 4x + 53

Answer 1

C: y = -3x +3

Explanation:

Lines that are parallel have the same slope have so the slope of the line in -3, now we have to find the y-intercept, we can do this by substituting -2 for x and 9 for y and solve for b

9 = -3(-2) +b

9 = 6 + b

b = 3

So the line that is parallel to y = -3x -8 and goers through the point (-2,9) is y = -3x + 3 or answer C

Answer 2

y = -3x + 3

Explanation:

Since the line is parallel, it has the same slope. Plug the point you have into the equation y - y1 = slope (x -x1) to get your answer, which should be y = -3x +3
