Question

Plz help me plz plz plz plz I need to do it plz

Answer 1

y = 2x

Explanation:

Step 1: Pick two points on the line. For this one, logical points would be (0, 0) and (1, 2).

Step 2: Use these points and the slope formula to solve for the slope.

`m =(y_2-y_1)/(x_2-x_1)`

`m =(2-0)/(1-0)`

`m = (2)/(1)`

`m=2`

Step 3: Use this slope in the equation of a line.

`y=mx+b\\y=2x+b`

Step 4: Substitute a point into the equation of a line to solve for the b value. I will use point (0, 0).

`y=2x+b\\0=2(0) +b\\0=0+b\\b=0`

Therefore the function is y = 2x.

Answer 2

y = 2x

Explanation:

Slope = 2

Equation

y = 2x

Double check

if x = 1, y = 2*1 = 2

if x =2, y = 2*2 = 4

and so on....
