Yes your graphing right
Y intercept is -2 and the slope is 1
Y = X + -2
I think you mean "Equivalent ratios" if that makes sense, but anyways in order to find Equivalent ratios, you have to either multiply or divide both the numerator and denominator of a given ratio by the same number.
For example: Create a table with the numbers of boys and girls
1. Boys: 3
2. Girls: 5
Next set this as a fraction like this
1. 3/5
Then to find equivalent ratios, multiply both numbers by two and you should get
6/10 (because we multiplied the 3/5 by 2)
Next write 6/10 along the chart of boys and girls
(Write them as fraction like this: 3/5 and 6/10)
Ratio of:
Boys: 3, 6
Girls: 5, 10
and there you have found an equivalent ratio.
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
<span>First let’s create a word problem using the factors 9 and 10.
=> Maria bought 9 couple shirts and the price of each pairs of couple shirt is 10 dollar. Now, find the total amount that Maria spent for the 9 couple shirt that she bought.
Now, let’s show the solution to our given word problem
=> Number of pairs of couple shirt = 9
=> Amount of each pairs of couple shirt = 10 dollars
=> 9 x 10
=> 90
Thus Maria paid 90 dollars in total.</span>
