I need help with this math question can someone help

C)  y = -3.5x+10

Explanation:

The y intercept is 10 which means (0,10) is another point on this line.

Use the slope formula for the two points (0,10) and (5,-7.5)

m = (y2-y1)/(x2-x1)

m = (-7.5-10)/(5-0)

m = (-17.5)/(5)

m = -3.5

We have m = -3.5 as the slope and b = 10 as the y intercept.

We go from y = mx+b to y = -3.5x+10 which is why the answer is choice C.

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition. 

Aand b is what i think
