The point of intersection between the two systems in a, is (6,9). the point of intersection between the two systems in b, is (0,2). to find them all you have to do is just solve for the first variable and then substitute that answer into the other equation.

A line is graphed below. Write an equation in the form y = mx + b that represents this line

galben [10]

<h3>Explanation</h3>

Slope-Intercept form

$y = mx + b \\ m = slope \\ b = y - intercept$

Calculate the slope with two given coordinate by using rise over run.

$\begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}$

These two coordinate points are part of the graph and can be used to find the slope.

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

Substitute the coordinate points in the formula.

$m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2}$

Therefore, the slope is 2.

Rewrite the equation in slope-intercept.

$y = \frac{1}{2} x + b$

Calculate the y-intercept by substituting any given points in new rewritten equation.

$(x,y) = ( 0,2)$

I will be substituting these coordinate points in the equation.

$y = \frac{1}{2} x + b$

Substitute x = 0 and y = 5 in the equation.

$2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b$

Therefore the y-intercept is (0,2).

Rewrite the equation.

$y = \frac{1}{2} x + 2$

<h3>Answer</h3>

 $\large \boxed{y = \frac{1}{2} x + 2}$

What is 23/8 as a decimal?

trasher [3.6K]

To write 23/8 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 23 by 8 what we write down as 23/8 and we get 2.875 

And finally we have: 
23/8 as a decimal equals 2.875

dedylja [7]

Answer:

There are 6 more girls than boys

Step-by-step explanation:

boys :girls : total

2 3 2+3 = 5

There are 30 total students

30/5 = 6

Multiply each number by 6

boys :girls : total

2*6 3*6 5*6

12 18 30

There are 18 girls and 12 boys

18-12 = 6

There are 6 more girls than boys
