Question

Identify the slope and the y -intercept of the equation 4x−3y=12 a. The slope is 4/3, , and the y-intercept is (0, 4) b. The slope is 4, and the y-intercept is (0, 12) c. The slope is 4/3, and the y-intercept is (0, −4) d. The slope is −4/3, and the y-intercept is (0, 4) .

Answer 1

Write the equation in slope-intercept form y = mx + b:

4x − 3y = 12
−3y = −4x + 12
y = (4/3)x − 4

So the slope is 4/3 and the y-intercept is (0, −4). Answer: c.
