Answer:
m= 2
b=9
Step-by-step explanation:
-4, 1 -3,3
put it into y2-x2 divided by y1-x1
y2= 3
x2= 1
y1= -3
x1=-4
3-1 divided by -4--3= 2/1 =2x
get one of the points either -4,1 or -3,3
If you use -4,1 -4=x 1=y
put it into y=mx+b and you get 1= -4(2)+b simplify
1=-8+b add 8 to other side b=9

Answer:
y=3x+6
Step-by-step explanation:
Coordinate:(-1,3)
Slope: 3/1=3
Formula=y-y^1=m(x-x^1)
y-3=3(x--1)
y-3=3(x+1)
y-3=3x+3
+3 +3
y=3x+6
