Explain how you can use the slope of formula to write an equation of the line that passes through (3,-2) and has a slope of 4.

Slope formula is m= (y2-y1) / (x2-x1)

we have one point of (3,-2) but we need one more point

we can get another point by using our slope 

so if we go "up four" and to the "right 1" in our heads we know that one more point would be (4,2)

now we have our 2 points we can plug them into the formula

m = (2+2) / (4-3)
