Y=2x+4 would start at the y intercept of 4, so (0,4) then go up 2 since it’s a positive slope and go over one, up two over one. And repeat.
Y=3x+2 would start at the y intercept of 2 and go up 3 over 1 and repeat, then graph the line!
Answer:
x = -5
y = 1
Step-by-step explanation:
-4(-5)-1=24
25-1=24
24=24
Answer:
Sandy needs 
of carpet to build a scratching post for her cats
Step-by-step explanation:
Sandy needs to calculate the surface area of the cylinder
The surface area of the cylinder is equal to
we have
----> the radius is half the diameter
assume
substitute the values

================================================
Explanation:
If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.
Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.
The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
