Multiply x and 3

Multiply x and 1

The x just gets copied along.

The answer is x

3*x evaluates to 3x

Because of the minus sign

3x becomes - 3x

The answer is -3x

Multiply y and 2

Multiply y and 1

The y just gets copied along.

The answer is y

2*y evaluates to 2y

-3*x-2*y evaluates to -3x-2y

The answer is -3x-2y-2

-3*x-2*y-2 evaluates to -3x-2y-2

so the first one is right

PLEASEEEE ANSWERRR FASTTTT!!!!!!!!!!What is the equation of the line whose graph is shown?

Mamont248 [21]

Answer:

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

To find m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

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

m = $\frac{-1-1}{-1-1}$ = $\frac{-2}{-2}$ = 1

y = x ← is the equation of the line → A
