Answer:
Yes. (see below)
Step-by-step explanation:
First, find the slope of the line. You can do that by using the slope formula:
y2 - y1
m = ----------
x2 - x1
Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).
4 - 3
m = ------
2 - 0
1
m = --- = 1/2
2
Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.
The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.
Now, plug them in:
y = mx + b
y = 1/2x + 3
To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:
13 = 1/2 (20) + 3
13 = 10 + 3
13 = 13
This is true, so the point (20, 13) is on this line.
Answer:
Riley's hourly rate is $10
Step-by-step explanation:
Riley earned $5 for 1/2 of an hour babysitting. What is her hourly rate?
1/2 of an hour = $5
1 hour = $x
Cross Multiply
1/2 × x = $5 × 1
x = $5 ÷ 1/2
x = $5 × 2
x = $10
Hence, Riley's hourly rate is $10
I’m gonna go with B, 525m=c
Explanation:
m represents months
c represents total cost
C has to be on its own side of the equation for one. m is the number of months and you multiply this by the cost per month to find the total cost.
Hope this makes sense!!
