Answer:
You can put this equation into point slope formula which is…
y-y1= m(x-x1)
Whilst m is slope
x1 and y1 (x1, y,1)
So in this case lets find the slope first.
Slope is calculated by y2-y1/ x2-x1
Can be any point.
7-(-1) / 1-(-3)
Which is
2
Slope is 2
So plug it in.
y-(-1)= 2(x-(-3)
Solve
y+1= 2x+6
isolate y
Y=2x+5
Your equation is y=2x+5
