Answer:

Answer:

y = 13

Explanation:

You want to add the like variables:

(3x - y) = -1

+(-3x +3y) = 27

The x's cancel out:

2y = 26

Divide by 2 on both sides to get the y by itself and solve for y

y = 13

Write the equation of a line whose slope is 2/3 and crosses the y axis at (0, -5)

postnew [5]

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

$y=\frac{2}{3}x-5$

Step-by-step explanation:

We will use the slope intercept form of the equation to make an equation of the given line

The slope-intercept form is:

$y=mx+b$

Here m is the slope and b is the y-intercept

Given

m = 2/3

Putting the value of slope

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

The y intercept is -5 so we will put in the equation

$y=\frac{2}{3}x-5$

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

$y=\frac{2}{3}x-5$
