Question

Which of the following is the point and slope of the equation y - 15 = -2(x + 1)?

a) (-1, 15), -2

b) (1, 15), -2

c) (-1, -15), -2

d) (-1, 15), 2

Answer 1

The point and slope of the given equation y - 15 = -2(x + 1) are (-1, 15) and -2, respectively.

Step-by-step explanation:

The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Comparing the given equation y - 15 = -2(x + 1) with the point-slope form, we have y1 = 15 and m = -2.

Therefore, the point and slope of the equation are (-1, 15), -2.
