Wich equation representa the line shown on the graph?

y = 2x

Step-by-step explanation:

The equation of a line passing through the origin is of the form

y = mx ( m is the slope of the line )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

m = = = 2

y = 2x ← equation of line

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
