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
The point (-1,2) is in quadrant 2
Answer:
11 students
Step-by-step explanation:
We can see that there are 6 students with 3 siblings, 4 students with 4 siblings, and 1 student with 6 siblings.
Adding all of these together will tell us how many students have 3 or more siblings.
6 + 4 + 1 = 11
So, there are 11 students with 3 or more siblings.
Answer:
5 1/3 gallons
Step-by-step explanation:
Equation: 8 1/6 - 2 5/6
8-2=6
1/6-5/6= -4/6
6-4/6=5 2/6
Simplify:
5 1/3 gallons
