You want this in slope-intercept form, which is : y=mx+b

Where m = slope, and b = y-intercept

To find the slope, pick two points on the line given to us :)

I have decided to pick the points : (0, -4) and (4, -3)

To solve for the slope, we use the slope equation, which is : m = y₂-y₁ / x₂-x₁

** In this case, y₂ = -3 ; y₁ = -4 ; x₂ = 4 ; x₁ = 0 **

Simply plug everything in :)

m = -3 - (-4) / 4 - 0

Simplify.

m = -3 + 4 / 4

Simplify.

m = 1/4

So, our slope is 1/4.

Now we need to find the y-intercept.

** Remember : The y-intercept is the point in which our given line passes (goes) through the y-axis **

So, please go look at our line. As you can see, our y-intercept is -4, as that is the point in which our line passes through the y-axis.

So, the slope is 1/4 & the y-intercept is -4.

Slope-intercept form : y = mx + b

Plug everything in.

y = 1/4x - 4 is your final answer.

~Hope I helped!~

kirill115 [55]

Answer:

I'm pretty sure that the answer would be 229/236.

Step-by-step explanation:

Ok so. Since the results of the test is 229 for a girl and the results for a boy is 7. So i'm pretty sure what to do is combine both the results and keep that as the denominator. And then the numerator will be the result. So in this case the numerator would be 229 and the denominator would be 236.

I hope this helped, have a great day!!!

The route to an ancient pyramid is 79 miles long.

Nostrana [21]

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:

3(20) + x = 79

x = 19 miles

The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.

Answer:

-4 and 4

Step-by-step explanation:

<u>Method 1</u>

Apply Difference of Two Squares Formula: $a^2-b^2=(a+b)(a-b)$

Given $x^2-16=0$

Rewrite 16 as 4²

Therefore, $a^2=x^2$ and $b^2=4^2$

$\implies a = \sqrt{x^2}=x$

$\implies b=\sqrt{4^2} =4$

$\implies x^2-16^2=(x+4)(x-4)$

$\implies (x+4)(x-4)=0$

$\implies (x+4)=0 \implies x=-4$

$\implies (x-4)=0 \implies x=4$

<u>Method 2</u>

Given equation:

$x^2-16=0$

Add 16 to both sides:

$\implies x^2-16+16=0 + 16$

$\implies x^2=16$

Square root both sides:

$\implies \sqrt{x^2}=\sqrt{16}$

$\implies x=\pm4$

Therefore, x = -4, x = 4
