Question

Write an equation in slope-intercept form of the line through point P(6, –1) with slope 4.
A. y = 4x – 1  
 
 B. y = 4x – 25  
 
 C. y + 1 = 4(x – 6)  
 
 D. y + 6 = 4(x – 1)

directrix · Answer

The general equation for the slope-intercept of a line is y = mx + b where b is the y-intercept and m is the slope of the line.

directrix · Answer

In this problem, m = 4 and the line passes through (6.-1).

y = mx + b
y = 4x + b

directrix · Answer

y = 4x + b

From the point coordinates, x = 6 and y = -1

So, (-1) = 4*(6) + b

directrix · Answer

(-1) = 4*(6) + b

Solve the above equation for b. --> @Melody_
