Area of AAFD= 54centimeters squared
1. the slope of the line is rise/ run
pick two points change in y/ change in x
we go up 7 and to the right 5
up and right are positive (down and left are negative)
m = 7/5
2. The y intercept is where we cross the y axis (x=0)
it is called b
b=7
(0,7)
3. y=mx+b
y = 7/5 x+7
this is in slope intercept form
Answer:
$45
Step-by-step explanation:
In order to create a multiplication equation, we would need to use a single variable that represents the amount that each friend will pay. This can be represented by the variable x. We multiply this variable by the number of friends which should equal the total of the TV with the tax included. Like so...
$210 + $15 = 5x
Now that we have the equation we can go ahead and solve it by adding the total and the tax, and then dividing both sides by 5 in order to isolate x.
$210 + $15 = 5x
$225 = 5x
$45 = x
Finally, we can see that each friend will pay the same amount which is $45
Answer:
5
Step-by-step explanation:
To find the slope we will use the slope formula:
They give us the points of (0,1) and (-2,-9) in the equation. Let's label each thing to fit the equation:
y2 = -9
y1 = 1
x2 = -2
x1 = 0
Now, plug it all in to the equation:
Therefore, the slope is 5.
