Answer
y = 2x
Explanation
The first thing is to find the gradient of the line.
Gradient = Δy/Δx
= (4--2)/(2--1)
= 6/3
= 2
Now a general point (x, y) and one of thegiven points.
(y - 4)/(x - 2) = 2
y - 4 = 2(x - 2)
y = 2x - 4 + 4
y = 2x + 0
y = 2x
Answer:
A
Step-by-step explanation:
The interception of the two lines is the solution point.
Yes you are correct
60 * 360 / 40 = 540
Answer:
Function
Step-by-step explanation:
Two different X's could equal the same Y value so this is a function. Remember if there's multiple of the same input (x) equalling different outputs (y) then it is not a function. If there's multiple inputs (x) equalling the same output (y) it's just coincidence and works.
