Subtract 7x from 8x then add 25 to 5 then divide what you get when you subtract 7 from 8 by what you get when you add 25 to 5 and that's your answer ( add x to the answer).

    7x + 5 = 8x - 25
         -  5 = -8x -5
-------------------------------
7x - 8x = - 5 - 25

-1x = - 30
-----   -------
 -1        -1

x = 30

A line is parallel to y= 4x-2 and intersects the point (5,-11). what is the equation of this parallel line?
mina [271]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

Putting the value of slope

to find the value of b, putting (5,-11) in the equation

Putting the value of b

Hence,

The equation of line parallel to given line is: y=4x-31

Keywords: Equation of line, slope
