Answer:
Step-by-step explanation:
slope = y₂-y₁/x₂-x₁
1-7 = -6. Here if two numbers have different sign, then subtract and put the bigger numbers sign for the result.
Answer: $70
Step-by-step explanation:
11 x 15 = 165 - this is the amount she gets for all 11 of the extended warranties
935 - 165 = 770 - this is the amount she gets for all 11 of the televisions
770 / 11 = 70 - this is the amount she gets for 1 television
Answer:
2,
Step-by-step explanation:
The vertex is the very highest or very lowest point. X coordinates are listed first, then Y.
First isolate y by adding x to both sides in y-x=3 and getting y=x+3
Step 1: substitute x+3 for y in 3y=x+6 to get 3(x+3)=x+6
Step 2: distribute 3x+9=x+6
Step 3: subtract like terms 2x=-3
Step 4: divide x=-3/2
substitute -3/2 for x in y=x+3 to get
y=-3/2+3
y=3/2
answer: y=3/2 x=-3/2
Do you have a picture of the graph? They formula put into y=mx+b is y=4/3+2
so the y intercept is 2 and the slope will be going upwards :)
