Question

Which equation does the graph below represent? (5 points)

A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 20 to positive 20 in increments of 4 for each grid line. A line is shown passing through the ordered pairs negative 4, negative 16 and 0, 0 and 4, 16.

A: y = 4x

B: y = fraction 1 over 4 + x

C: y = 4 + x

D: y = fraction 1 over 4 x

Answer 1

y=4x...I did a test on it.

Explanation:

Answer 2

The slope is the change in y over the change in x.

Slope = (0 - -16) / (0- -4)

Slope = 16/4

Slope =4

You would then multiply the slope by the variable.

The answer is y = 4x
