Question

Which of the following is the correct point-slope equation for the line that

passes through the point (-3,-9) and is parallel to the line given by
y= 2.5x - 20?
O A. y + 3 = 2.5(x + 9)
B. y + 9 = 2.5(x + 3)
C. y - 9 = 2.5(x-3)
O D. Y-3 = 2.5(x-9)

Answer 1

B

Explanation:

since the gradient of y=2.5x -20 is 2.5

thus the gradient of the slope point eqn would also be 2.5 as they are parallel

And with the given pt(-3,-9) where x = -3 and y = -9

y +9 = 2.5(x +3)
