Answer:
y = 3x+1
Explanation:
Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:
7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.
we now can make the first part of the equation:
y = 3x + b
Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).
-5 = 3x-2 + b
you get:
-5 = -6+b
which is equal to:
b = 1
So, putting b back in the equation, you get:
y = 3x+1
