Question

Which equation represents the graphed function?

Answer 1

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

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

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1)

m = $\frac{1-3}{1-0}$ = - 2

Note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - 2x + 3 ← equation of line → A

Answer 2

Answer:

the answer is A. y = -2x+3
