Write an equation in slopeintercept form of the line through

Write an equation in slope-intercept form of the line through point P(6, –1) with slope 4.

A. y + 6 = 4(x – 1)

B. y + 1 = 4(x – 6)

C. y = 4x – 25

D. y = 4x – 1

Solution

The slope is given by 4

The point is (6,-1)

The equation is y-y1 = m(x-x1)

y - (-1) = 4(x-6)

y+1 = 4(x-6)

The answer is B
