Question

Which equation represents the graph of the linear function?

A. y= -1/3x+1
B.y=-3x-1
C.y=3x+1
D.y=-3x+1

Answer 1

The answer is D because the y intercept is a positve one, and when you find the slope, it is -3. To find the slope, you can either pick two points on the graph and do y1 -y2 over x1-x2, or you can count the slope on the graph.
