Answer:
a)It is a vertical line with an undefined slope
b)It is a vertical line with an undefined slope
c)7/4
d)-7/4
Step-by-step explanation:
The formula for gradient of a line is given as;
m=Δy/Δx
where Δy = y₂-y₁ and Δx=x₂-x₁
<u>For L₁ </u>
x=2
It is a vertical line with an undefined slope
<u>For L₂</u>
x=-3
It is a vertical line with an undefined slope
<u>For L₃</u>
The points on the line are : (0,-3) and (4,4)
m= Δy/Δx
m= 4--3/4-0
m=7/4
<u>For L₄</u>
The points on the line are : (0,-3) and (-4,4)
m=Δy/Δx
m=4--3/-4-0
m=7/-4
m= - 7/4
Answer:
answer is A
Step-by-step explanation:
The formula for circumference of a circle using diameter is pi times "d". "d" means diameter. 3.14 x 16= 50.24
Answer: Y = 7/8x+ 2.25
Step-by-step explanation:
- you would subtract both y 7
- subtract both x -8
- y=7/8x+b
- 3= 7/8 x-2 +b
- 3 = 1.75 + b
- -1.75 -1.75
- 2.25 = b
