Ian and his family are driving to visit friends in another state. on the first part of the trip, they drive for 2 hr. at a constant rate of 60 mph. then they hit rush hour and slow down to a constant rate of 45 mph for the next hour. the last three hours of the trip, they drive at a constant rate of 55 mph. how many miles did ian and his family drive?

The equation that represents a slope of -5 and y-intercept of (0,1) is:

Step-by-step explanation:

The equation of a line can be described by a first order equation in the following format:

In which a is the slope of the line and b is the y-intercept.

Solution:

The problem states that the slope is -5, so:

y intercept is (0,1), so

The equation that represents a slope of -5 and y-intercept of (0,1) is:

Why the others are wrong?

Here, the slope is -1, and the y-intercept is (0,-5).

For this option, the slope is 1 and the y-intercept is (0,-5).

Is it 5x - 1? If so, the slope is 5, and the y-intercept is (0,-1).
