John walks his dog home from the vet. The graph shows the remaining distance from his house as a linear function of x, the number of minutes he spent walking. Find the domain and range of the graph. ​

Step-by-step explanation:

domain is the input, or the x values,   range is the output, or y values

x goes from 0 to 40  so that's the domain

y  goes from 0 to 4 so that the range

Y is more than or equal to 0, but less than or equal to 4.

X is more than or equal to 0, but less than or equal to 40

Step-by-step explanation:

there are no short passages to look at

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
