Answer:
Option D.) x + 2x − 3 = 26
Step-by-step explanation:
Let
x ------> the length of Nate's car
y ------> the length of Maya's car
we know that
x+y=26 -----> equation A
y=2x-3 ----> equation B
substitute equation B in equation A and solve for x
x+(2x-3)=26
3x=26+3
x=29/3 in
Find the value of y
y=2(29/3)-3
y=(58/3)-3
y= 49/3 in

Step-by-step explanation:
You've got five different problems in this photo ... four on top and the word problem on the bottom ... and they're all exactly the same thing: Taking two points and finding the slope of the line that goes through them.
In every case, the procedure is the same.
If the two points are (x₁ , y₁) and (x₂ , y₂) , then
the slope of the line that goes through them is
Slope = (y₂ - y₁) / (x₂ - x₁) .
This is important, and you should memorize it.
#1). (8, 10) and (-7, 14)
Slope = (14 - 10) / (-7 - 8) = 4 / -15
#2). (-3, 1) and (-17, 2)
Slope = (2 - 1) / (-17 - -3) = (2 - 1) / (-17 + 3) = 1 / -14
#3). (-20, -4) and (-12, -10)
Slope = [ -10 - (-4) ] / [ -12 - (-20) ]
=========================================
The word problem:
This question only gives you one point on the graph,
and then it wants to know what's the slope ?
What are you going to do for another point ?
A "proportional relationship" always passes through the origin,
so another point on the line is (0, 0) .
Now you have two points on THAT line too, and you can easily
find its slope.
