Answer: y = -4/3x + 0. Yes, that point lies on the line

Step-by-step explanation:

Use this equation, Δy/Δx and this one, y = mx + b. Or, change in the y value divided by the change in the x value.

-4 + 8 = 4

3 - 6 = -3

The slope, m, is -4/3. Now solve for b by plugging in the slope.

-4 = \frac{-4}3 (3) + b. B is equal to 0

To see if that point lies on the function, plug it in the equation and see if it is true. Multiply -4 x -3 to get 12, divide by 3 to get 4, then add 0. The equation says that 4 = 4, which is infact true

Answer:

<u> y=-4x/3</u>

<u> the point (-3,4) is on the line y= -4x/3</u>

Step-by-step explanation:

the points (6,-8) and (3,-4)

<em><u>a) (y- y1)/(y2- y1)=(x- x1)/(x2- x1) </u></em>

(y+8)/(-4+8)=(x-6)/(3-6)

(y+8)/4=(x-6)/(-3)

-3y-24=4x-24

<u>So, y=-4x/3</u>

b) (-3; 4)

4= -4*(-3)/3

4=4 it is true,

<u> the point (-3,4) is on the line y= -4x/3</u>

a. She used 1/10 of the spinach for a salad.

b. She used 1/2 pound of spinach for the salad.

We can solve each part of this problem by using a "fraction strip". The strip helps show a breakdown of what portion of spinach was used for each the party, family, and salad. See the attached image for a step by step example of how to multiply the fractions to find the correct portions.
