Answer:
y = 4x - 9
or y = 4x + -9
Step-by-step explanation:
First, you must find a point that intersects with the line
The point that intersects the line is: (3,3)
Second, you must do rise over run, to find out how far one point is from the other
Rise over run consists of the rise (the change in y, going up or down) divided by the run (the change in x, going from left to the right).
So, for this question, the slope would be up 4 and to the left 1 or 4/1 = 4
Then we must find the y-int
The y-int is the number that intersects the y-int
So, for this question it would be -9
You can't see the whole graph in the picture, but you can kind of see it intersect the number -9
So, we must put together the equation, which is y = mx + b
m = slope = 4
b = y-int = -9
So, the equation would be: y = 4x - 9 or y = 4x + -9
here is a graph with the equation
and another graph with rise over run
