Plug in the numbers wherever these letter are. Ex: 10x+5y. You would do 10x12=120 and 5x20=100. Add these two numbers to get 220. Hope this helps:)

Which point slope form equations could be produced with the points (3,2) and (4,6)
Anika [276]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given two points first find the slope of the line and use the formula

y - y1 = m( x - x1) to find the Equation of the line using any of the points given

Slope of the line using points

(3,2) and (4,6) is

m =  \frac{6 - 2}{4 - 3}   =  \frac{4}{1}  = 4

So the equation of the line using point

( 3 , 2 ) and slope 4 is

<h3>y - 2 = 4( x - 3)</h3>

Hope this helps you

What is the slope of a line that passes through (–4,–13) and (19,11)?
Anna11 [10]
For points (x1,y1) and (x2,y2)
slope=(y1-y2)/(x1-x2)

(-4,-13)
(19,11)
x1=-4
y1=-13
x2=19
y2=11

slope=(-13-11)/(-4-19)=-24/-23=24/23

Find the slope of a ski run that descends 15 feet for every horizontal change 24 feets
Diano4ka-milaya [45]

Answer: 5/8


Step-by-step explanation:


Slope is determined by dividing the amount of vertical movement by the amount of horizontal movement and then simplifying the answer. In this case it is 15/24. To simplify you need to find the least common denominator (LCD), which is 3, and divide both numbers by it. 15/3=5 and 24/3=8, so the answer is 5/8.
