I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
(8•40) + (8•5) = 320 + 40 = 360
BD is 18
XY is 4
IK is 8
DF is 16
Answer:
(–6, 10)
Step-by-step explanation:
Because the line is perpendicular its slope is the negative reciprocal of line FG. If we examine the graph and plot out the slope we see that it crosses point (–6, 10).
