Answer: You need to show the number line in order to get an answer.
Well do you know what a supplementary angles is ?
it is two angles that add up to 180 degrees
Right angles will be formed because in drawing
the perpendicular lines they all form right angles
to begin with. With several more draw it will
still be the same as if you are drawing one
the answer is -right angles
since the graph has direct variation as data in x axis increases y also increases.
so we need to find how many miles travelled per galloon .
we distance travelled per gallon =total distance travelled/galoons of fuel used.

for part b) slope=rise/run



slope of the graph is 2
4(2x raise to power 2-4-7x)
