Question

In the equation y = x +2, x represents Jean's age in years, and y represents the age of Jean's older sister, Rachel. Which is the graph of this equation? (please help)

Answer 1

C.

Explanation:

The equation is already in y = mx + b format. M means slope and b means is the y-intercept. Since we can see the slope is 1 and the y-intercept is 2, we can find the graph that matches this. In graph C, the line intercepts the y axis at the point 2 and the line goes up 1 on the y axis for every 1 on the x axis so it is true.
