Question

Determine the equation of the line with slope –4 that passes through the point M(-2,1) .

Select one:
a. y = -4x + 7
b. y = -4x - 7
c. y = 4x + 9
d. y = -4x - 9

Answer 1

y = mx + b
slope(m) = -4
(-2,1)....x = -2 and y = 1
now sub and find b, the y int
1 = -4(-2) + b
1 = 8 + b
1 - 8 = b
-7 = b
so ur equation is : y = -4x - 7 <===
