Answer:
C. y = 4x -6
Explanation:
The line intercepts the y-axis at -6, consistent with the first three answer choices.
It appears to have an x-intercept of about 1.5 (certainly, less than 2), so between that point and the y-intercept, there is a "rise" of 6 and a "run" of about 1.5.
Then the slope is rise/run = 6/1.5 = 4. This will be the x-coefficient in the slope-intercept form:
y = mx + b
y = 4x -6
