A line passes through the point and has a slope of . Write an equation for this line.

Hi Mandy;

Point-slope formula is...

y-y

_{1}=m(x-x_{1})m=slope

You can input the point provided either as (x,y) or (x

_{1},y_{1}). I always do the latter.Let's me provide an example.

slope -4/5

point (5,3)

y-3=(-4/5)(x-5)

y-3=(-4/5)x+4

Let's add 3 to both sides...

y-3+3=(-4/5)m+4+3

y=(-4/5)x+7

The equation is now in slope-intercept form...

y=mx+b

m is the slope.

b is the y-intercept, the value of y when x=0.
