Step-by-step explanation:

1. Find the total cost of apples first

1.99 * 3 = $5.97

2. Price of the bread

.89 * 2 = 1.78

3. Price of the box of cereal

3.99

4. Gallon of milk

3.19

5. Add all together

And you come up with 14.93 dollars

6. Subtract by 20

Please help me please !

Answer:

For the first one:

y = 2/3x + 1

For the second one:

y = -5x + 4

Step-by-step explanation:

As you may already know, in the y=mx+b equation format:

m = slope

b = y-intercept

On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.

And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.

Then, you can just leave the variables y and x alone.

Hope this helped!!

Use the given conditions to write an equation for the line in point-slope form. Passing through (2,-3) with x-intercept = -2

goldfiish [28.3K]

The equation for line is $y=-\frac{3}{4} x-\frac{3}{2}$

Explanation:

It is given that the line passes through the point $(2,-3)$ with x-intercept = -2

The x intercept is the value of x when y = 0.

Thus, it can be written in coordinate as $(-2,0)$

Now, we shall determine the slope using the points $(2,-3)$ and $(-2,0)$

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting, we get,

$m=\frac{0+3}{-2-2} \\m=-\frac{3}{4}$

Thus, the slope is $m=-\frac{3}{4}$

Now, we shall substitute the point $(2,-3)$ and slope $m=-\frac{3}{4}$ in the point-slope formula $y-y_1=m(x-x_1)$ , we get,

$y+3=-\frac{3}{4} (x-2)$

Multiplying both sides by 4, we get,

$4y+12=-3x+6$

Subtracting both sides by 12,

$4y=-3x-6$

Dividing both sides by 4, we get,

$y=-\frac{3}{4} x-\frac{3}{2}$

Thus, the equation of the line is $y=-\frac{3}{4} x-\frac{3}{2}$
