Answer:
The area of the triangle is 36 square units
Step-by-step explanation:
First you can make the graph to set up the problem. You then plot the point 3,6 (A). You then reflect this over the Y axis which would be the point -3,6 (B). Point A is then reflected over the X axis to give you 3,-6 (C). You then multiply their total lengths 12 and 6 which is 72. Then you divide 72 by 2 because it is a triangle to get 36
If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.

Let us fill the blank squares in the 10-frame by the yellow circles below to make 10s.
1. Fill the 3 blank squares with 3 yellow circles below to make a 10 and form a new fact 10 + 2. Now, we can easily add 10 and 2 to get 12.
2. Fill the 1 blank square with 1 yellow circle below to make a 10 and form a new fact 10 + 4. Now, we can easily add 10 and 4 to get 14.
Please refer attached figures for better understanding.
divide gallons used by time
4 3/8 = 35/8
2 1/2 = 5/2
35/8 / 5/2 = 35/8 * 2/5 = 70/40 = 7/4 (simplest form) = 1 3/4 gallons per hour
