Question

How do you graph `y = -½ x + 3` by plotting points?

Answer 1

See the explanation.

Explanation:

`y=-1/2x+3` is the slope intercept form of a linear equation.

Determine two points on the line by substituting values for `x` into the equation and solving for `y`. You only need two points for a straight line.

Table of Points
`x=0,` `y=3`
`x=6,` `y=0`

Plot the points and draw a straight line through the points.
