Graph the function f(x)= -3x. Please Help! Thank you so much

Answer 1

Either plot on graph paper or use a plotting program such as Excel.

To plot on graph paper write a row of x values across the paper, say

-5, -4, -3, -2, -1, 0, 1, 2, 3, 4

then write below it -3x values, so

15, 12, 9, etc.

Then plot these pairs on graph paper

(-5, 15), (-4, 12) etc.
