Answer:
y=2x+4
Step-by-step explanation:
If there's a y intercept, that's the b in y=mx+b (when x=0, the y is the b)
so we have part of the equation: y=mx+4
m=slope=y2-y1/x2-x1
Since you gave me 2 points, whether they're intercepts or not, we can use those to find slope
4-0/0-(-2)=4/2=2
slope=2
y=2x+4
