Simplify 9 - 7x - 7x to 2 - 14x

2 - 14x = 4

Subtract 2 from both sides

-14x = 4 - 2

Simplify 4 - 2 to 2

-14x = 2

Divide both sides by -14

x = -2/14

Simplify 2/14 to 1/7

x = -1/7

Find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3.

sammy [17]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut point with the y axis.

By definition, if two straight lines are parallel then their slopes are equal. Thus, the slope of the line sought will be $m = 2.$

$y = 2x + b$

We substitute the given point to find b:

$2 = 2 (-1) + b\\2 = -2 + b\\2 + 2 = b\\b = 4$

Finally the line is:

$y = 2x + 4$

Answer:

$y = 2x + 4$
