I couldn’t see the whole picture so I’m not sure if I could really help I’m sorry maybe next time
It would be 125.4 . Find this by isolation the variable on the right side by using the multiplication property of equality. Multiply both sides by 57 so it would leave you with (125.4 = z). Hope this helps! :)
Step-by-step explanation:
x=2 y=0
x= -2 y= -4
y=mx+b
b= 2
-4 = -2m +2
-2m= -6
m=3
y= 3x +2
.......
x=0 y=4
x=2 y= 2
y=mx+b
b=4
2=2m+4
2m= -2
m= -1
y = -x +4
Y-12=-10, add 12 to both sides, the answer is y=2
It is not a function because it does not pass the vertical line test. For every x value there must be only 1 y value but this graph is not a function because there are 2 y values for every y value.
