Perpendicular line has slope that multiplies to -1
paralel line has same slope
y=mx+b
slope=-7/4
perpendicular
4/7
(-7,-2)
-2=4/7(-7)+b
-2=-4+b
add 4 both sides
2=b
y=4/7x+2
paralel
y=-7/4x+b
-2=-7/4(-7)+b
-2=49/4+b
minus 49/4 from both sides (-2=-8/4)
-57/4=b
y=-7/4x-14.25
perpendicular
y=4/7x+2
paralel
y=-7/4x-14.25
Answer: B. Square

- All sides of a square have the same length
- All four angles of a square = 90°
- A square has two parallel sides
Answer:
C
Step-by-step explanation:
Since the company earns $0.05 for every mile, we would multiply m by 0.05. We also add it with 30 since it is a base charge. This makes it C
It can't be A or B since that would mean the company earns $30.05 for every mile.
It can't be D since that would mean the company earns $30 for every mile with a base charge of $0.05.
