Answer:
b
(3, -2)
step-by-step explanation:
needs to be y = mx + b
x + y = 1
-x -x
y = -x + 1
y = x - 5 is already in form
using desmos
they intersect at (3, -2)
Neither, for lines to be parallel they have to have the same slope, and for lines to be perpendicular they have to be the negative reciprocal of the slope of the other line. In this case, the line perpendicular to the line with slope m=10 would be m=1/-10 or -1/10
Page 1 is B, page 2 is B, page 3 D, page 4 D ( prity sure not 100%), page 5 you posted it twice
X - 2y = -24
x - y = 4
Isolate x in the first equation by adding 2y to both sides.
x = -24 + 2y
Now plug in this value of x into the second equation.
(-24 + 2y) - y = 4
Solve. Combine all like terms, 2y - y.
-24 + y = 4
Add 24 to both sides to isolate y.
y = 28
Now plug y back into the first equation to find x.
x - 2(28) = -24
x - 56 = -24
Add 56 to both sides to isolate x.
x = 32
The solution is (32, 28).
