What equation is shown by the graph below?

Answer:
y=x+4
Step-by-step explanation:
First, if you want to put the equation into slope intercept form (y=mx+b) you can easily find the b value by seeing that the graph crosses the y axis at (0,4) meaning the y-intercept is 4 (the +4). Next, to find the slope, you can take any two points on the graph (for this example I'll use (2,6) and (4,8)) and plug them into the formula to find the slope [tex]\frac{8-6}{4-2}[/tex] to get a slope (m value) of 1.
