Question

Which linear equation represents the graph? *

y = -3x - 2
y = 3x + 2
y = -1/3x + 2
y = 1/3x - 2

Answer 1

y = -3x - 2

Explanation:

At first glance, it is clear the slope is negative as the y value decreases as the x value increases.

The rise/run looks to be -3/1, so the slope is -3

The y value at x = 0, or y-intercept, is -2

The correct equation would be y = -3x - 2

Answer 2

y=-3x-2

Explanation:

y=mx+b

y=-3x+b

y=3x-2

m is the slope, b is the y intercept
