Step-by-step explanation:
Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.
Pluging in and chugging Point A into each equation should tell us what the equation should be.
<u>Option 1</u>
x - y = 1
-3 - 2 = 1
-5 ≠ 1
We see here that -5 does not equal to 1. Therefore option 1 is incorrect.
<u>Option 2</u>
x + y = -1
-3 + 2 = -1
-1 = -1
We see here that -1 does equal to -1. Therefore option 2 is correct.
<u>Option 3</u>
x + y = 1
-3 + 2 = 1
-1 ≠ 1
We see here that -1 does not equal to 1. Therefore option 3 is incorrect.
<u>Option 4</u>
x - y = -1
-3 - 2 = -1
-5 ≠ -1
We see here that -5 does not equal to 1. Therefore option 4 is incorrect.
We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
