Answer:
use points (0,5) and (1,7)
see below for graph
Step-by-step explanation:
First, we'll turn the equation from point slope form (y-y1=m(x-x1)) into slope intercept form (y=mx+b)
y+1=2(x+3)
do the distributive property
y+1=2x+6
subtract 1 from both sides
y=2x+5
We'll need two points to graph the line.
You can subsitute x or y as any number you like and solve the equation.
For example:
if x=0:
y=2(0)+5
y=5
so the point would be (0,5)
and if x=1
y=2(1)+5
y=2+5
y=7
point: (1,7)
Use the points (0,5) and (1,7)

Hope this helps!
