When you are doing an equation like this, multiply every variable by the next. For example, if you had how many ways could 5 colors be arranged, you would do 5 times 4 times 3 times 2 times 1, because there are 5 options for space 1, 4 for space 2 and so on. For this equation, the first coin you toss has 2 possible options, and so do the other 3 coins. So 2 times 2 times 2 times 2 = 16. The answer is A. I hope this helped! Please give brainliest!
Answer:
true
Step-by-step explanation:
The answer is c, right 4 down 3
1) y=3x-4
When x increases by 1, y increases by 3 so the slope is rise/run → 3
y-int is -4 bc y-value is -4 when x=0
2)y=-3x+4
When x increase by 2, y decreases by 6 so the slope is rise/run → -3
y-int is 4 bc y-value is 4 when x=0
3)y=-1/3x+4
When x increase by 3, y decreases by 1 so the slope is rise/run → -1/3
y-int is 4 bc you now have the equation y=-1/3x+b and u just have to plug in random point from the graph, so ex, 6 into x and 2 into y. You can get 4 as b in the equation.
4)y=1/3x-4
When x increases by 6, y decreases by 2 so the slope is rise/run → 1/3
y-int is -4 bc u do the same thing as 3)
For ex, plug in 6 for x and -2 for y and you can get -4 as the b in the equation.
