We can obviously see the -2 point on the y - axis where the value of x is 0.
So the y-intercept is -2.
Now to simply find the slope.
Using the formula:
y2 - y1/x2 - x1
Find two random points (preferably in the same quadrants):
(4, 1) and (8, 4)
Now we plug in:
8 - 4/ 4 - 1
4/1
4
Hence, the equation is y = 4x - 2.
Thanks.
