Question 1140453
I'm kinda lost on how to get my b for number 7, I know it's where it intercepts y but how do I get that from what I'm given. and I'm lost on number 8 as well.

5)  Find the slope of the line through the points (1, 4) and (5, 5).
m = (y2 - y1)/(x2 - x1)
m = (5  -  4)/(5-1)
m = 1/4

6) Write in point-slope form, , the equation of the line through the two points given in #5.
(y - y1)=m(x - x1)
y  -  4 = (1/4)(x  -  1)
========================

7)  Convert the equation that you wrote in #6 to slope-intercept form, .
y =(1/4)x+?
---
y = (1/4)x - (1/4) + 4
y = (1/4)x + 15/4
--------
8)  Convert the equation that you wrote in #6 to standard form, , where A, B, and C are integers and A > 0.
4y = x + 15
x - 4y + 15 = 0
