What is the equation of the line x–3y=18 in slope-intercept form?

1 answer:

4 0

Solve the equation for y

x-3y= -18

-3y = -18-x

now, divide both sides with -3

y = (-18-x)/-3

y = 6 +x/3

your slope is 1/3

and y-intercept is 6

$2(x+5)=3x+1 \\2x+10=3x+1 \\-x=-9 \\x=9$

$3y-4=6-2y \\5y=10 \\y=2$

$3(n+2)=9(6-n) \\3n+6=54-9n \\12n=48 \\n=\frac{48}{12}=4$

Hope this helps.

-2(-1) + 7y = -54

2 + 7y = -54

7y = -56

y = -8

When x = -1, y = -8.

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3

Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

EFJL is dilation of ABIK
AB has a length of 12
EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25
