Graphing Equations Practice

Graph the linear equation with an x-intercept of 2 and a y-intercept of -5

Answer explanation

The x-intercept is on the x-axis. Plot the point (2,0).

The y-intercept is on the y-axis. Plot the point (0,-5)

Graph the linear equation with x-intercept of -8 and y-intercept of 10

Answer explanation

The x-intercept is on the x-axis. Graph the point (-8,0).

The y-intercept is on the y-axis. Graph the point (0,10)

Graph the linear equation with initial value of 6 and -4 as the rate of change.

Answer explanation

Initial value is the y-intercept. Graph the point (0,6). The rate of change is the slope. The slope is -4 which can be expressed -4/1. This means move down 4 for every 1 unit you move to the right. The slope can also be expressed as 4/-1. In this case you move 4 down for every 1 unit you move to the left.

Label each line to its equation.

Graph. y = 2/3x - 3

• a

• b

• c

• d

y = 2x + 5

• y = 2x + 5

• y = -2x - 5

• y = -2x + 5

• y = 5x - 2
