Answer

The intercepts are

y-intercept = (0, 4)

x-intercept = (-2, 0)

The graph of the line is presented below

Step-by-step explanation

The intercepts of a line include the points where the line crosses the axes.

y = 2x + 4

when x = 0

y = 2x + 4

y =2(0) + 4

y = 0 + 4

y = 4

First intercept is the y-intercept and it is a point on the line = (0, 4)

when y = 0

y = 2x + 4

0 = 2x + 4

2x = -4

DIvide both sides by 2

(2x/2) = (-4/2)

x = -2

Second intercept is the x-intercept and it is a point on the line = (-2, 0)

To plot the line, we will mark these two points on the graph and connect them to obtain the line.

The graph of the line is presented above under 'Answer'

Hope this Helps!!!
