Lines that are parrellell presume to have the same slope.

So if we just calculate the slope of a function or a line we should be good.

s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}

Now put in the data from the coordinates of the points A(3,-1)\wedge B(1,7)

s=\dfrac{7-(-1)}{1-3}=\dfrac{8}{-2}=\underline{-4}

The form of a function now looks like: f(x)\vee y=-4x+n

From here we are no longer required to calculate anything more. Leave n alone.

The solutions are the equations of the form above.

That would mean:

y=-4x \\y=-4x+8 \\y+1=-4(x+1) \\y-6=-4(x-3)

Hope this helps.

Answer:

Louise used the most flour.

Step-by-step explanation:

Okay so first off 12% of 5 pounds would be 0.6 pounds. So we can put that Stan used 0.6 pounds. Then 0.11 of the total flour would be the same as 11% of 5 pounds, which is 0.55 pounds. So Liam used 0.55 pounds. We already know that Louise used 0.7 pounds of flour so we can order it like this.

Louise=0.7 Pounds

Stan=0.6 Pounds

Liam=0.55 Pounds

shepuryov [24]

Answer:

9

Step-by-step explanation:

first integer = x

second integer = x+2

third integer = x+4

8x=3(x+2+x+4)-4

8x=3(2x+6)-4

8x=6x+18-4

8x=6x+14

2x=14

x=7

second integer=7+2=9
