Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Lines AB and CD
NARA [144]

Lines AB and CD are parallel. Using the given coordinates

The equation of line CD is y=-\frac{1}{4}x+7

Given :

Lines AB and CD are parallel. The coordinates of point A are (-2,5), the coordinates of point B are (6,3),the coordinates of point D are (8,5)

When two lines are parallel then their slopes are equal

Lets find the slope of AB using the given points

A is (-2,5)  and B is (6,3)

Find slope using slope formula

slope m =\frac{y_2-y_1}{x_2-x_1} =\frac{3-5}{6+2} =-\frac{1}{4}

Slope of AB is -\frac{1}{4}

Slope of AB  and CD  are same

Slope of CD is -\frac{1}{4}

Now we find equation of line CD y=mx+b

Use point slope formula

y-y_1=m(x-x_1)\\

use the given point D(8,5) and slope m

Substitute the values

y-5=-\frac{1}{4} (x-8)\\\\y-5=-\frac{1}{4}x+2\\y=-\frac{1}{4}x+2+5\\y=-\frac{1}{4}x+7

The equation of line CD is y=-\frac{1}{4}x+7

Tell whether the equation has one, zero, or
11Alexandr11 [23.1K]
So starting with the question which is
4x-3=2x+13
All you have do is subtract 2x from 4x which is 2x
So now the equation will become
2x-3=13
Minus 3 on both sides So 2x is left over
2x=16
X=8
