Answer:
y=3x+4
Step-by-step explanation:
Slope-intercept form is written as y=mx+b
m = the slope
slope is rise over run or (y2-y1)/(x2-x1). We need to choose which y value is y2 and the corresponding x value is the x2. If -2 is y2, then:
x2 = -2
y1 = 1
x1 = -1
then plug in the values.
(-2-1)/(-2-(-1))
-3/-1 = 3
m =3
then plug in values for the first equation. you can use any point on the line.
y = 3x+b
4 = 3*0 +b
4=0+b
b = 4
then write it with out x or y
y = 3x+4
