Question

Write an equation for the line that passes through (-4,0) with a slope of 1/2

Answer 1

Hi Zane,

 

The standard form of  line is written as y = mx + b, where m is the slope.

So we are given the slope and the coordinates o a point that this line passes through. All we need to do is plug in the x, y values and slope to solve for b.

when x = -4, y = 0

0 =(1/2)*-4+ b 

b = 2

then the equation of the line is

y = (1/2)x + 2
