Answer:
c = 208.8
Step-by-step explanation:
a. <em>To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.</em>
b. <em>You need to move the 7.2 to the other side. So, </em><em>multiply</em><em> both sides by 7.2, because it's being divided, so multiplying will cancel it out.</em>
c: <em>Then, multiply 7.2 by 29. (The * symbol means multiply)</em>
d. c. = 208.8 <em>The answer is 208.8, which is rounded to the tenths place.</em>
Hope this helps! I tried to explain it in detail. :)
Answer:
Step-by-step explanation:
First we need to find the slope of the line. We can plug in both coordinates in to the slope formula.
The slope formula is:
So I will use (-3,4) as the first coordinate, and (7,-1) as the second coordinate.
x₁ = -3
y₁ = 4
x₂ = 7
y₂= -1
I will plug in these values to find the slope.
Now that we know the slope is -1/2, we can plug in the slope and a point into the point slope equation. Then we can solve for y.
I have attached an image of what this graph should look like. Since the slope is -1/2, the y value should decrease by 1/2 every time you move over by 1 on the x axis. And since the equation says "+5/2" we know we have to shift the graph up by 5/2. The y-intercept will be 5/2.
I added another image that shows how to graph an equation using the equation y=mx+b
