3a - 4b = 21
check (-2 , -3)
3(-2) -4(-3) =21
-6 +12 = 21
6 does not = 21 so NO
check (0 , 7)
3(0) -4(7) =21
0-28=21
-28 does not equal 21 so NO
check (-3 , -2)
3(-3) -4(-2) =21
-9 +8 = 21
1 does not = 21 so NO
check (7 , 0)
3(7) -4(0) =21
21 = 21
Choice D
Answer:
<h3>The picture in the attached figure.</h3><h3> </h3><h3>we know that </h3><h3> </h3><h3>Area of the triangle is equal to </h3><h3 /><h3> A= ( b×h ) /2</h3><h3> </h3><h3>in this problem </h3>
<h3> A=47 in²</h3><h3> </h3><h3> b=x</h3><h3> </h3><h3> h=x</h3>
<h3>so </h3><h3> 47 = X * X / 2</h3>
<h3> x² = 94 </h3><h3>

when x=0: y=-3(0), y=0
when x=2: y=-3(2), y=-6
(0,0) and (2,-6) are two points on the line. Connect them and extend the line.
