You can make use of the slope-intercept form of a line which is:
y = mx + b
Substitute m and the coordinates of a point in the line to find b,
-2 = (2/5) (5) + b
b = -4
The equation is
y = (2/5) x - 4
In standard form:
(2/5)x - y = 4
2x - 5y = 4
24 miles to on one gallon of gas
Distance/gallons
258/10.75
24
99 km ... 9 liters
x km ... 12 liters
If the relationship is proportional, we have
from where
The answer is 132 kilometers.
18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.
20.) The formula for the area of a parallelogram is:
A = b • h
110.5 = 13h
110.5 / 13 = 8.5
110.5 = 13 • 8.5
And because this is a measurement of the height, not the area, it is just meters (m)
So, the full answer is 8.5 m
I hope this helps!
