<h3>Answer:</h3>

$x=2$

<h3>Explanation:</h3>

Represent the sentence mathematically. $2(x-3)=-2$

Distribute. $2x+(2*-3)=2x-6=-2$

Add 6 on both sides. $2x=-2+6=4$

Divide both sides by 2. $x=2$

Answer:

Slope (m) = $\frac{y}{x} = \frac{2}{3} = 0.66666666666667$

Step-by-step explanation:

$0 = arctan (\frac{y}{x}) = 33.69006752598°$

X = 4 – 1 = 3

Y = 4 – 2 = 2

$Distance (d) = \sqrt{x^2+y^2}= \sqrt{13} =3.605551275464$

Equation of the line:

y = 0.66666666666667x + 1.3333333333333

$y=\frac{2}{3}x+\frac{4}{3}$

When x=0, y = 1.3333333333333

When y=0, x = -2
