Factor 9x² + 25 over the set of complex numbers

I think this is the answer

y=30x+75

Step-by-step explanation: We need to first find the slope using the formula (y2-y1)/(x2-x1)

What that means is you can pick two given points in the table and subtract one of the (y) from the other point's (y) and subtract the (x) of on elf those points from the other points (x) I'll use the points

(5, 225) and (7,285).

(285-225)/(7-5)

simplify

60/2

30

The slope is 30

Now we need to find the y-int. Take a random point from the table and plug it into the y=30x+b. I'll use (5, 225) again.

225=30(5)+b

225=150+b

-150 from each side

75=b your y-int is 75
