Answer:
<em>x = 15; y = 8; m<Q = 83</em>
Step-by-step explanation:
2x + 7 = x + 22
x + 7 = 22
x = 15
8y - 4 = 4y + 28
4y - 4 = 28
4y = 32
y = 8
2x + 7 + 8y - 4 + m<Q = 180
2(15) + 7 + 8(8) - 4 + m<Q = 180
30 + 7 + 64 - 4 + m<Q = 180
m<Q + 97 = 180
m<Q = 83
Answer:
I got 9/12 for the slope
Step-by-step explanation:
I just looked up the slope equation which is Y1 - Y2/X1 - X2 = m
Then you assign your numbers with X1, Y1 (10,4) X2, Y2 (-2,-5) and solve.
I think :P
