# How do you graph the line #y = 4/5x + 3#?

##### 2 Answers

Assign value for x to find y.

#### Explanation:

If x is zero,

If x is 1,

If x is 2,

etc.

You can graph now:

graph{((4x)/5)+3 [-8.04, 11.96, -2.4, 7.6]}

Refer to the explanation.

#### Explanation:

Graph:

You only need two points to graph a straight line. The most convenient points are the x- and y-intercepts.

**Y-intercept:** value of

Substitute

**The y-intercept is the point #(0,3)#. Plot this point.**

**X-intercept:** value of

Substitute

Multiply both sides by

Subtract

Divide both sides by

Switch sides.

**The x-intercept is the point #(-15/4,0)# or #x=(-3.75,0)#. Plot this point.**

You now have two points plotted. Draw a straight line through the points.

graph{y=4/5x+3 [-10, 10, -5, 5]}
