Y = -4x + 8

First you need to find the slope of the line.

The slope formula is m = y2-y1/x2-x1

If you plugged in the points it would be m = -4-4/3-1

so m = -8/2 = -4

so the slope is -4

now we need to write the equation of the line

for this u use point slope form

the formula for that is y-y2=m(x-x1)

so if you plug it in it would be:

y-(-4)=-4(x-3)

now you solve

y+4=-4x+12

y+4-4= -4x+12-4

y = -4x + 8

and now you have the slope of the line

I hope this helps! :)

Answer:

-2/5

Step-by-step explanation:

p(x) = 5x + 2

plug p(x) = 0

5x + 2 = 0

5x = - 2

x = - 2/5

Bonita spent $8.94 on groceries. She bought a gallon of milk for $4.29 and 3pounds of sliced turkey. How much does 1 pound of sl

Vesna [10]

<h2>Information</h2>

$8.94 spent in total on groceries

Gallon of milk = $4.29

3 pounds of sliced turkey bought = ?

<h2>Explanation</h2>

Subtract the total amount spent on groceries with what items you have prices for (in this case the gallon of milk):

$8.94 (total spent) - $4.29 (gallon of milk) = $4.65 (for 3 pounds of sliced turkey)

Next, divide the price for 3 pounds of sliced turkey with however many pounds Bonita bought (in this case, 3 pounds):

$4.65 (total for 3 pounds of turkey) ÷ 3 (pounds of turkey) = $1.55 (per pound of turkey)

<h2>Solution</h2>

Each pound of turkey costs $1.55

A water truck is filling a swimming pool. The equation that represents this relation is y=18.25x where y is the number of gallon

QveST [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, however, one of the requirements of this question while I searched, was to make a table and sketch the equation.

If this is the case, then, all you need to do is take the equation, Assume some values for x, and compute the values of y. Then, you can do the graph.

I begin with value from 0 to 10.

This is the example of calculations:

x = 0

y = 18.25*0 = 0

for x = 0, we get y = 0. For x = 2:

y = 18.25 * 2 = 36.5

If we keep doing this, we should get a straight line. See the graph and attached table. If the question is asking another thing, then please get back to me to answer it.
