Figure #5 shows 5 squares which I would assume means (5, 5)
In the table you have the point (3, 7)
From this you can find the slope: (7 - 5)/(3 - 5) = -1
Completions of table:
x y
0 10
1 9
2 8
3 7
4 6
5 5
6 4
Rule/Equation:
y = -x + 10
Graph: Plot the ordered pairs from the table
A) Slope = 5, for the y intercept plug 0 into x, so y=5(0)+10 =10. So the y-intercept is (0,10)
c) I added the graph below. First you plot the y intercept, (0,10). Then count 5 up and 1 right and plot a point because the slope is (5/1) "slope is easy and fun, rise over run." You can go the opposite way too, 5 down and 1 left and then plot a point. Plot 5-7 points. The x-axis is time, because that is the independent variable and the y-axis is baskets of berries because that is the dependent variable.
1)
x + 2y = 21
+ -x + 3y = 29
--------------------------
5y = 50
y = 10
x + 2(10) =21
x = 1
2)
6x + 6y = 30
+ 15x - 6y = 12
-------------------------------
21x = 42
x = 2
6(2) + 6y = 30
6y = 18
y = 3
Answer: 18.75 for each girl
Step-by-step explanation:
First you take the unit rate 2.50 multiply by 5.
2.50 x 5 = 12.50
12.50 x 3 = 37.50
37.50 / 2 = 18.75
