The answer is B.
The reason behind it being that since the sides of the entire patio are given, you can multiply them and get the area of the entire patio, then you can subtract the area of the bench, which in this case is 12 because 2 times 6 is 12. Since you can’t solve for (x+20) or (x+10), you can multiply them by themselves. This would give you the equation (x+20)(x+10)-12.

A line passes through (−1, 7) and (2, 10). which answer is the equation of the line?

mart [117]

First you need to find the slope of the line. So what you need to do is y^2-y^1 / x^2-x^1

(x^1, y^1) (x^2, y^2)
( -1, 7) ( 2, 10)

10-7/ 2- (-1)
3/3=1
slope is 1

I got 8 as the y intercept. Reason how is that I made a table. And what I did was go back instead of going forward.

x y
-1 7
0 8
1 9
2 10

The answer would be x= 1 y= x + 8 y=8 But the answer choice you listed for A. would not match up the 2 coordinate you gave. Make sure a. should be x= 1 y= x + 8 y=8, not -x y= 8-x y=8
