Answer:

2x + 5

Step-by-step explanation:

I am assuming you are talking about a linear function. If it is, then the equation would be:

2x + 5.

Hope this helps!

Answer:

y = 2x + 5

Step-by-step explanation:

For this example, I used the slope-intercept form, y = mx + b, where m represents the slope and b represents the y-intercept.

In order to find the equation, we must find the slope and y-intercept.

<h3>Finding m</h3>

The slope can be found with the formula:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}, where the x and y variables represent different x and y values from the given points.

Substituting in values from the points, we get:

m = \frac{-1 + 9}{-3 + 7}\\\\m = \frac{8}{4}\\\\m = 2

<h3>Finding b</h3>

In order to find the y-intercept, we must substitute the slope back into the original equation:

y = 2x + b

After this, we must also substitute either of the two points. Both will give the correct answer, but (-3, -1) will be used for this example.

-1 = 2(-3) + b\\-1 = -6 + b\\5 = b

<h3>Finding the equation</h3>

After this, all that must be done is to substitute the values for b and m back into the original equation.

y = 2x + 5

To check our work, we can substitute in either of the given points. For demonstration purposes, (-7, -9) will be used.

(-9) = 2(-7) + 5\\-9 = -14 + 5\\-9 = -9

The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.

Answer:

6/12 or half

Step-by-step explanation:

this would be the answer because the lowest common denominator of 4 and 3 is 12 so you'd multiply them you'd get 12 then multiply 2 and 3 and get six therfore the answer is 6/12 or 1/2
