For the first one, if you replace x and y with the values given, it won't check in the first equation.
You can check in each equation or you could find the slope
-3 - 1 divided by 1-3
-4/-2 = 2 = m
Find b: -3 = (2)(1) + b
b = -5
I agree with the second one.
what is an equation in slope intercept for. for the line that passes through the points 1,-3 and 3,1
y=3x+1 **
y=x-3
y=2x+5
y=2x-5
For the equation -4y=8x what is the constant of variation?
-4
-2 **
1
2
