Slope is (change in y)/(change in x). If you have a slope of -2/3 the change in y is -2 and the change in x is 3. Find the point (-2, 1) on the xy plane. Change the y component by -2 (move down 2 grid lines) then change the x component by 3 (move to the right 3 grid lines). If you repeat this process in both directions then draw a line through the points you'll have a line with slope -2/3 which passes through the point (-2, 1). The equation of this line is: y=-2/3x-1/3
All you have to do is replace every x with 2 and then solve:

-9x(2) + 11x - 7 =
(-9 × 2 × 2) + (11 × 2) - 7 =
-36 + 22 - 7 =
-14 - 7 =
-21
The answer is -21.
Hope that helps!
Vera's change will be $1.94
Baby potatoes= 1.62
Green beans= 2.54
Amount spent on potatoes= 1.62×2.625
= 4.25
Amount spent on beans= 2.54× 1.5
= 3.81
The change can be calculated as follows
= 3.81 + 4.25
= 8.06
10-8.06
= 1.94
Hence the change is $1.94

Ratio being 3:5:7
longest being 56 so
7x=56
x=8
multiply the other lengths by 8
3*8=24
5*8=40
making the final
24:40:56
- Evaluate [5 - (5 - 5(2 - 5) + 2)] + 6
![\sf [5 - (5 - 5(2 - 5) + 2)] + 6](https://tex.z-dn.net/?f=%20%20%5Csf%20%5B5%20-%20%285%20-%205%282%20-%205%29%20%2B%202%29%5D%20%2B%206)
Subtract 5 from 2 to get -3.
Multiply 5 and -3 to get -15.
The opposite of -15 is 15.
Add 5 and 15 to get 20.
Add 20 and 2 to get 22.
Subtract 22 from 5 to get -17.
Add -17 and 6 to get -11.
