Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
Answer:
X = 108.
Step-by-step explanation:
Heights are equal, So equation will be,

So, solving the eq.
Subtract 4 from both sides ,

Divide 3 to both sides,

Squaring both sides,

Add 8 to both sides,

Answer:
.8>63%
Step-by-step explanation:
Slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)
we have the points (-1,3) and (4,-7)
x1=-1
y1=3
x2=4
y2=-7
slope=(-7-3)/(4-(-1))=-10/5=-2
answer is D
