The slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
In this case the slope is...
1
The y-intercept is...
(0, -4)
Plug these numbers in for m and b respectively:
y = 1x + (-4)
y = x - 4
Hope this helped!

Step-by-step explanation:
Answer:
The gallons of fuel car need to travel 30 km is <u>0.75</u> approximately .
Step-by-step explanation:
Given:
The car can travel 25 miles per gallon. (1 mile = 1.6 km)
Now, we need to convert 25 miles into km .
25 miles = 25 × 1.6 km
= 40 km
So, the car can travel 40 km per gallon.
Then, we find out in 1 km how many gallons are used:



Now, we find out how much gallons of fuel will the car need to travel 30 km:
Gallons of fuel the car need to travel 30 km = 
=
.
Therefore, the gallons of fuel car need to travel 30 km is 0.75 approximately.

2(3x+16)
Step-by-step explanation:
Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4
4(x + x + 7) − 2x + 8 − 4
When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38
When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44
Plug in x=1 and check with each expression
6x + 11 =6(1) +11= 16
3(x + 7) = 3(1+7)= 3(8)= 24
2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2
2(3x + 16) = 2(3(2)+16)= 44
3x + 16= 3+16= 19
