You want k such that
.. (10 +k)/2 = 7
Multiplying by 2, we have
.. 10 +k = 14
Then
.. k = 14 -10
.. k = 4

a line passes through (-4,7) and has a slope of -3/2 write and equation in point slope for for this line

Sophie [7]

Hey!
Our point slope formula is y-y1 = m(x-x1)
Therefore, we can plug our values from the slope and the set of points.
We have:
y-7 = -3/2(x--4)
Subtracting a negative is the same thing as adding, so we have:
y-7 = -3/2(x+4)
Hope this helps!

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

$y=3x-9+4$

$y=3x-5$
