SOLUTION: can you show me how to put something into point-slope form and how to then convert it back to slope intercept form. the equation is this "write the equation in slope-intercept form

Question 398682: can you show me how to put something into point-slope form and how to then convert it back to slope intercept form. the equation is this "write the equation in slope-intercept form of the line going though the point (5,9) with the slope of 2"
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
write the equation in slope-intercept form of the line going though the point (5,9) with the slope of 2
----------
Form: y = mx+b
You know y = 9 when x = 5 and you know m = 2; solve for "b":
---
9 = 2*5 + b
b = -1
---
Equation:
y = 2x-1
