Remember starts at zero slope is up 4 right 1
Y= 4/1x+0
Y=4x
Answer:
Step-by-step explanation:
y = mx + b
slope(m) = 1/4
(-1,-4)...x = -1 and y = -4
now sub and find b, the y intercept
-4 = 1/4(-1) + b
-4 = -1/4 + b
-4 + 1/4 = b
-16/4 + 1/4 = b
-15/4 = b
so the equation in slope intercept form is : y = 1/4x - 15/4
but we need it in general form : Ax + By + C = 0
y = 1/4x - 15/4.....multiply everything by 4 to get rid of fractions
4y = x - 15......subtract x and add 15 ...to both sides
4y - x + 15 = 0 <=== general form
Answer:
8
Step-by-step explanation:
Plug in 3 for x and simplify
2(3)^2 - 10
18-10
=8
Answer: 61.6%
Step-by-step explanation:
The afternoon humidity average is 20% of the morning average.
The morning average is 77% so the afternoon average must be:
= Morning average * ( 1 - percentage decrease)
= 77% * (1 - 20%)
= 77% * 80%
= 61.6%
