The y intercept in this graph is (0,1) ad the only equations that fit this are a and c. To figure out whether it is a or c, find the slope. The line of the equation is going up, so he slope is positive. Equation c has the positive slope. EQUATION C
The y intercept of the line is (0,-1). This would make the last number a negative one as well. The line's directionis positive so the only equation that fits is D
