Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:
Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
Answer:
x=-18
Step-by-step explanation:
What you have do do is look at the word <em>difference. </em>
Difference means subtraction so you will subtract x and -37.
x-(-37)=19. You will then make the negative a positive and subtract 37 from both sides.
x=-18 is your answer.
Answer:
Let's make "b" the amount in the account.
A withdrawal means a reduction in the balance. So we have
b - 40
letter C would be your option here are your reasons
5x/4-2=3/2x-4
5x/4-2=3x/2-4
5x-8=6x-16
-8=6x-16-5x
-8=x-16
-8+16=x
8=x
x=8
hope this helps :)
Answer:
<h2>
The slope is <u>
3</u></h2><h2>
To graph it you should put a point at any of the points that are in the table. Some easy ones are (0,0) and (2,6)</h2>
Step-by-step explanation:
To find the slope you need to follow the formula shown below.
Slope (m) = ΔY/ΔX
Now solve
ΔY = 6 – 0 = 6
ΔX = 2 – 0 = 2
Write as a fraction
6/2
Convert to a number
6/2 = 3
And you have your slope. Now you just have to plot the points on the graph. As I said before, you can use any two points from the table.
