Answer:

a. y = 3

b. x = 1

c. y-intercept = 5

d. x-intercept = -2.5

e. 2

f. y = 2x + 5

Explanation:

Based on the graph, we can see the point where x is -1, y = 3.

Based on the graph, we can see the point where y = 7, x = 1.

Based on the graph, we can see the y-intercept is 5.

Based on the graph, we can see the x-intercept is -2.5.

To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).

Slope =
(rise)/(run)

=
(5-3)/(0-(-1))

=
(2)/(1)

= 2

The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5
