14. Write the equation in slope-intercept form that passes through the two points. (1, 2) and (3,-8) ​

y=5x+7

Step-by-step explanation:

If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt  form is y=mx+b. So the equation is y=5x+7.

let (x1,y1)=(1, 2)

and(x2,y2)=(3,-8)

Step-by-step explanation:

we have

y-y1=(y2-y1)(x-x1)/(x2-x1)

y-2=(-8-2)(x-1)/(3-1)

y-2=-10(x-1)/2

y-2=-5(x-1)

y-2=-5x--5

y+5x=5+2
