The line is not in slope intercept form, so you need to get y by itself
15x -3y = 90
Subtract 15x
-3y = -15x + 90
Divide by -3
y = 5x -30
So, the slope (x) is 5/1.
I hope that helps!
A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x^-2" just means "x2, but underneath, as in 1/x^2.
-4^-2 means the power -2 is only applied to 4 and not the negative sign. -4^-2 = -(4^-2), which is equal to -1/16.
Whereas, (-4)^-2 means the power -2 affects on both negative sign and 4. For example, (-4)^2 is equal to (-4 * -4) which is just 16. Moving on, with (-4)^-2 equals to 1/(-4*-4) = 1/16.

X = -1/15y+7/3

Answer:
0
Step-by-step explanation:
f(x) = y
To find f(2), it means to find the value of y when x = 2.
From the graph, when x = 2, the corresponding y-coordinate = 0.
Therefore,
f(2) = 0
