Answer:
m=0
Step-by-step explanation:
m=y2-y1/x2-x1
m=1/2-1/2/-2-7
m=0/-9
m=0
Answer:
(x, y) = (-4, -15)
Step-by-step explanation:
Perhaps you want the solution to ...
y = 3/4x -12
y = -4x -31
Equating the two expressions for y gives ...
3/4x -12 = -4x -31
3/4x = -4x -19 . . . . . add 12
3x = -16x -76 . . . . . multiply by 4
19x = -76 . . . . . . . . . add 16x
x = -76/19 = -4 . . . . divide by 19
y = (3/4)(-4) -12 = -15 . . . . use the first equation to find y
The solution to this system of equations is ...
(x, y) = (-4, -15)

This expression would be written as x/-2
When we write expressions of sentences like this, we need to separate out the different terms.
Quotient means to divide.
A number is written as x when we don't have a variable.
-2 is -2.
x/-2
