The ordered pairs for the intercepts are as follows:
x intercept = 9/2
y intercept = -18
In order to find either of these you must put 0's in for the other variable. So, to find the x intercept, we start by putting 0 in for y.
y = 4x - 18
0 = 4x - 18
-4x = -18
x = 9/2
To find the y intercept, we put a 0 in for x.
y = 4x - 18
y = 4(0) - 18
y = 0 - 18
y = -18

Answer:
72°
Step-by-step explanation:
The external angle E is half the difference of subtended arcs CG and DF.
E = (CG -DF)/2
2E = CG -DF . . . . . . multiply by 2
DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values
arc DF = 72°
(-2,8),(-1,5),(0,2),(1,-1),(2,-4) are points of the line.
1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.
