Question

the point slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1). What is the slope-intercept form of the equation for this line

Answer 1

y= 1/2x + 2.5

Explanation:

We already have the point-slope form of the line.

Convert into Slope Intercept form:

y-3=1/2(x-1)

`y-3=(1)/(2)x -0.5\leftarrow \text {Distribute}\\y-3+3=(1)/(2)x-0.5+3\leftarrow \text {Subtraction Property of Equality} \\\boxed{y=(1)/(2)x+2.5} \text { OR } \boxed{y=(1)/(2)x+(5)/(2)}`
