On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4). What is the equation of the line th

Novay_Z [31]

Answer:

$y=3x-5$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

(-3,2) and (0,1)

The slope m is

$m=(1-2)/(0+3)=-1/3$

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of its slopes is -1)

The slope is

$m=3$

step 3

Find the equation of the line in point slope form

we have

$m=3$

$point(3,4)$

$y-4=3(x-3)$ ----> equation in point slope form

Convert to slope intercept form

$y=3x-9+4$

$y=3x-5$

213 is 30% of what amount

WITCHER [35]

Start by calling the unknown amount 'x'. We can then set up a relationship to represent the question:

$213 = (30\%) \times x$
or
$213=0.3x$

and then solve for x, by dividing both sides of our equation by 0.3

$\frac{213}{0.3}=\frac{0.3x}{0.3}$
$710=x$

213 is 30% of 710

To check: $710 \times 0.3 = 213$
