Answer:
Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:
Combine the values:
Find the value of the fraction:
M is -3.
The equation so far is 
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
Answer:
6.30$
Step-by-step explanation:
If you add 7.80$ and 7.80$ that come to 4 hot dogs,
The rest of the money is how much one soda cost ( 2.40$ ),
Dividing that 7.80$ by 2, To only have one hot dog, would put you at
3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30
7.80 | 17.00 | 7.80/2 | 2.40
+ 7.80 | - 15.60 | 3.90 | + 3.90
15.60 | 2.40 | | 6.30
Answer:
sss
Step-by-step explanation:
Hi there!
Use PEMDAS:
Evaluate inside of parenthesis:
(264 + 3 × 7)
Multiply:
(264 + 21)
Add:
285
Divide by 3:
285 ÷ 3 = 95
Slope: (y2-y1)/(x2-x1)
(6-8)/(4-2) = -2/2 = -1
The slope is -1
