3. Trapezoid- only one pair of parallel sides
4. Parallelogram- opposite sides are parallel and equal in length and opposite angles are equal
5. Rhombus- all sides have an equal length, opposite sides are parallel, and opposite angles are equal
6. Kite- have two pairs of sides, each made up of adjacent sides that are equal in length. Angles are equal where pairs meet.
7. Isosceles Trapezoid- have a pair of opposite parallel sides that are equal in length.
To figure out where each crosses the x and y axis simply plug in 0 for y and x respectively.
x intercept is where y = 0
y intercept is where x = 0
a) x intercept
ax + b(0) = c
c = ax
x = c/a so the x intercept is (c/a, 0)
y intercept
a(0) + by = c
0 + by = c
y = c/b, so the y intercept is (0,c/b)
Jus repeat the process for part b
b) x intercept
ax - 0 = c
x = c/a, so the x intercept is the same, (c/a , 0)
y intercept
0 - by = c
y = -c/b, so the y intercept is different from before (0, -c/b)

Answer:
Plumber A has greater initial fee
Step-by-step explanation:
Plumber B:
Hourly charge = 160 - 105 = $55
Initial charge = 105 - 55 = $50
Equation: y = 50 + 55x
