Answer:
y=4x+8
Explanation:
to find the slope you look at the pattern from both the input(x) and output(y). in this case the input was increasing by 1 each time and the output was increasing by 4 each time. the formula for slope is delta y/delta x so the slope comes out to be 4/1. and the y-intercept is found by looking at the table. where the x is 0 the corresponding y value is the y-intercept. for this equation is 8. then you just put it into the slope-intercept formula: y=mx+b
