Question

How do you graph `y=-2x+3` by plotting points?

Answer 1

see explanation.

Explanation:

Choose any values of x and substitute them into the equation to obtain corresponding value for y

`x=0toy=0+3to(0,3)larrcolor(red)" y-intercept"`

`x=-2toy=4+3=7to(-2,7)`

`x=2toy=-4+3=-1to(2,-1)`

Plot these 3 coordinate points and you have the graph.
