Answer
a) y = 8x + 3
f(x) = 8x + 3
b) y = 2x - 3
f(x) = 2x - 3
Step-by-step explanation
Expressing equations in a function format includes leaving y on the left hand side and the rest on the right hand side.
a) -8x + y - 3 = 0
y = 8x + 3
f(x) = 8x + 3
b) 10x - 5y = 15
-5y = -10x + 15
Divide through by -5
(-5y/-5) = (-10x/-5) + (15/-5)
y = 2x - 3
f(x) = 2x - 3
Hope this Helps!!!
