Answer:
4) y = 2x - 7
Step-by-step explanation:
First we have to find the slope by using the following formula....
let (3, - 1) be 
, let (8, 9) be 
, and m be the slope, then....
Now that we know the slope we can find the equation of the function by using point-slope for of the function which look like this.....
??? what type of question is that??
Answer:
The temperature in the greenhouse was at least 68 degrees before the heater stopped working.
Step-by-step explanation:
It was at 68 then it dropped by 2 degrees.
10. 8x+4y=4. y=mx+b
-8x. -8x
4y=-8x+4
÷4. ÷4. ÷4
y = -2x +1
slope = -2. y-int= 1
11. slope is changing y over changing x
m = (y2 -y1)/(x2-x1) (0,-1) x1 = 0, y1=-1
(-4-(-1))/(-2-0) (-2,-4) x2 = -2, y2 = -4
(-4 + 1) / (-2)
-3/-2 = 3/2 answer is 3/2
12. b because negative cause it flip in x axis and it become flatter because of the fraction.
13. 2y =8-8x
÷2. ÷2 ÷2
y = 4 - 4x
