Question

Hiro painted his room. After 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint.

Let y represent the area (in square meters) left to paint after x hours.
Which of the following information about the graph of the relationship is given?

Slope and x-intercept

Slope and y-intercept

Slope and a point that is not an intercept

x-intercept and y-intercept

y-intercept and a point that is not an intercept

Two points that are not intercepts

Answer 1

Slope and a point that is not an intercept

Explanation:

Answer 2

Slope and a point that is not an intercept

Explanation:

Let

x ----> the time in hours

y ----> the area (in square meters) left to paint

we know that

Hiro paint at a rate of 8 square meters per hour

The rate is equal to the slope of the linear equation

we have the point (3, 28) ---> After 3 hours of painting, he had 28 square meters left to paint.

therefore

we have

Slope and a point that is not an intercept
