Given the equation:

y = 4x - 5

Use the slope intercept form:

y = mx + b

Where m is the slope and b is the y-intercept.

To plot the points, first make a point on the y-intercept, y = -5

At y-intercept, x = 0.

Thus, we have the point (0, -5)

Let's find the value of y, when x = 1.

y = 4(-1) -5

y = 4 - 5 =

y = -1

When x = 1, y = -1

We have the point (1, -1)

When x = 2

y = 4(2) - 5

y = 8 - 5

y = 3

When x = 2, y = 3

We have the point (2, 3)

Thus, mark the following points:

(0, -5)

(1, -1)

(2, 3)

Then connect the plotted points with a straight line.

We have the graph attached below:
