1. y=7-3x
4x+2(7-3x)=16
4x+14-6x=16
-2x=2
x=-1
-3+y=7
y=10
(-1,10)
2. x=2y
2(2y)+2y=4
4y+2y=4
6y=4
y=2/3
x-2(2/3)=0
x-4/3=0
x=4/3
(4/3,2/3)
3 times I think................
Here is the graph of x-y=4. According to this, the x intercept is (4,0), and the y intercept is (0,-4) :)
Answer: Slope is the measure of the steepness of a line. It can be calculated with the equation rise/run or change in y/change in x.
Step-by-step explanation:
3 different sizes.
3 different colors.
Total outcomes: number of sizes x number of colors.
3 x 3 = 9
There are 9 total outcomes.
