<em>5 - 20 = 2n ≈ 15</em>

<em>Subtract 5 from 5 and 20 .</em>

<em>2n = 15 </em>

<em> 15 ÷ 2 ≈ 7.5</em>

Can someone please help me witch is the answer 20 points to the one who can answer first
ladessa [460]

First, let's find the slope.

Slope = (7 - (-3)) / (2 - 0) = (7 + 3) / 2 = 10 / 2 = 5

So far our equation looks like: y = 5x + b

Leta plug one of the points into our equation to find b.

-3 = 5(0) + b

Simplify.

-3 = b

The equation is: y = 5x - 3

Answer choice B is correct.
