It’s the first answer, both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
1/2 of x +4
=1/2(2)=1.
1+4= 5
2+6=8
1/2(2)=1.
8-1=7
7-2=5

<h2>Writing an Equation of a Line in Slope-Intercept Form</h2><h3>
Answer:</h3>
![y = [ -2 ] x + [ 1 ]\\](https://tex.z-dn.net/?f=y%20%3D%20%5B%20-2%20%5D%20x%20%2B%20%5B%201%20%5D%5C%5C)
<h3>
Step-by-step explanation:</h3>
<em>Please refer to my answer from this Question to know more about Slope-Intercept Form: <u>brainly.com/question/24599351</u></em>
We must first find the slope.
<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>
We can see the marked points,
and
, are on the line.
Solving for the slope:

Now we can now solve for the
-intercept.
<em>Please refer to the second paragraph of my Answer from this Question to know more about y-intercepts: <u>brainly.com/question/24606058</u></em>
We can see that the line intersected the
-axis at
so
.
It would be 8:5.
Ratios are very simple. There're basically just writing one number per the other number, exept instead of writing per, you write : or /.
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b
y = -25x +250
