Question

How do you graph the line with slope -3 and `y`-intercept -2?

Answer 1

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

Explanation:

First plug in to slope-intercept form `y=mx+b` (m is slope and b is y-intercept):
`y=mx+b\rArry=-3x+(-2)`
`\rarry=-3x-2`

Input table with x and y values...
`{:(x,y), (0,-2), (1,-5), (2,-8), (3,-11), (4,-14):}`

then plot to get the graph
