Answer:
1st is y = -7x-58, 2nd is -89.
Step-by-step explanation:
First, the slope intercept for is y = mx+b. M is the slope, b is the y intercept. You know the slope is -7, so then just plug in the point for x, y and you'll get b = -58 once you cancel everything out.
So y = -7x-58.
For 27. just plug in the values. -3^3 is -27 * 3 which is -81 and then -12 and add 4 and you get -89.
