Question

The slope of the line that contains the points (-2, 10) and (3, -5) is -3. What is the y-intercept?

Answer 1

Answer:

The y-intercept of this line is (0, 4)

Step-by-step explanation:

Given that the slope of this line is -3, we know the general form of its equation is y = -3x + b.  Arbitrarily choosing the first point, (-2, 10), and substituting -2 for x and 10 for y, we find the y-intercept as follows:

10 = -3(-2) + b, or

10 = 6 + b, or

b = 4  (Answer C)

The y-intercept of this line is (0, 4)
