Answer:
Put a point at (-7,0) and another at (0,-2)
Step-by-step explanation:
2x+7y=-14
Plug in 0
2(0)+7y= -14
7y=-14
y=-2
same thing for x
2x+7(0)=-14
x=-7
Just use the division property of equality: divide 60 by -16 and you will get the value of x

Answer:
8
Step-by-step explanation:
Apparently, you want to evaluate ...
0.1m +8 -12n
for m = 30 and n = 1/4.
Put the numbers where the corresponding variables are and do the arithmetic.
= 0.1×30 +8 -12×(1/4) = 3 + 8 -3
= 8
