D, because if u plug it in both equation, u will get the same solution.
y=x-1

2=2

y=-3x+11
2=-3(3)+11
2=-9+11
2=2

Hope this helps!

Ten plus eight times a number a equals eleven times another number d minus six solve for a
svet-max [94.6K]
So your equation would be 8a+10=11d-6 First: you would combine like terms so normally you would take away the smaller number. So to cancel out the negative 6 you added you add positive six to the negative 6 so you would get 0 and whatever you do to one side you have to do to the other so you would do 10 + 6. Your new equation would be 8a+16=11d. Now you do -16 to both sides. So your new equation would be 8a= 11d - 16. Now you divide by 8. So your final equation would be a=11d-2.

A line has a slope of −5 and contains the point (−2, 4).
viva [34]
Plug them into point-slope form.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

Plug in what we know:

y - 4 = -5(x + 2)

So one of our answers is C.

Now distribute -5 into the parenthesis:

y - 4 = -5x - 10

Add 4 to both sides:

y = -5x - 6

Add 5x to both sides:

5x + y = -6

So the other answer is B.
