Question

How do you solve for y and graph `y+2x=3`?

Answer 1

As below.

Explanation:

`y + 2x = 3`

`y = -2x + 3`

When `x = 0`, y-intercept `= 3` coordinates `(0, 3)`

When `y = 0`, x-intercept `= 3/2` coordinates `(3/2, 0)`

Knowing two points, we can draw the graph.

graph{-2x + 3 [-10, 10, -5, 5]}
