Answer:
Student 1.
Step-by-step explanation:
Okay, for this one, for it to be linear, the x has to be adding or subtracting the same amount each time (same goes for y). You have to remember that the x and y do not correspond, only the sides themselves. As you can tell, Student 1 goes up by 1 on the x side each time, and on the y side, it goes up by 5 each time. The other graphs don't have linear equations. I hope this helped, if you need me to evaluate more, just ask!

Answer:
x=6,y=-11
Step-by-step explanation:
y=-3x+7
x=-2y-16
Substitute the second equation into the first every place you see an x
y=-3(-2y-16)+7
Distribute
y = 6y+48 +7
Combine like terms
y = 6y +55
Minus 6y from each side
y-6y = 6y-6y+55
-5y = 55
Divide by -5
-5y/-5 = 55/-5
y = -11
Now we need to find x
x=-2y-16
x = -2(-11) -16
x =22-16
x = 6
x=6, y= -11
Answer:
95 over 2
because if it is 47 you double that since the denominator is 2 then you add the numerator and now you have your answer.
8/5 = 20/x
8x = 20(5)
8x = 100
x = 12.5
