Aline passes through (2,8) and (4,12) which equation best represents the line

Well to find this answer, you would have to know the formula of a line, or also known as slope intercept form-- "y= mx+b" 

1) Let's find the slope between the two points! (Use the y1-y2 over x1-x2 slope formula) 

y1-y2
= slope formula. Use the points 2,8 and 4,12
x1-x2 

12-8       4           2
 =    =      = our slope is 2! 
4-2         2           1
                     ^ Here we simplify 

2) Now we know our slope is 2! Substitute this into the y=mx+b formula 

y=2x+b

3) Take one of the points we used for finding the slope and substitute it into our slope-intercept formula. That way we can solve for "b", our y-intercept. 

y=2x+b
8= 2(2)+b  MULTIPY 
8= 4 +b
-4  -4        SUBTRACT (inverse operations) 

4=b        SIMPLIFY (our final answer) 

4) Now we know our y-intercept! Substitute it into the slope-intercept form to get our line. 

y=2x+b
y=2x+4

5) Check your work by taking one of the points from above and substitute again! 

y=2x+b
12= 2(4)+4
12= 8+4
12=12

Our equation works! 

0.09 times bc of u do 58 divided by 607 u will get 0.09555189456
