Answer:
4=slope -9=y-intercept
Step-by-step explanation:
-9 is the y-intercept, where the x is 0 and in this case the y is -9, so on your graph, find where x is 0 and y is -9, put a dot there
4 is the slope, in other words 4/1 where 4 is y and 1 is x, so go up 4 from the y-intercept, and 1 from the x-axis, put a dot there
Draw a line between the 2 dots and that is your graph
