Question 426051: Find the equation of the line with m=1/2 and passing through (10,3). I created a line using the slope given and working backwards, using the points (10, 3). My answer was y=1/2x + 8 1/2 (using my graph paper). What did I do wrong?

Find the equation of the line with m=1/2 and passing through (10,3).
-------------
Use y = mx + b to find b
3 = (1/2)*10 + b
b = -2
-----------
y = (1/2)x - 2
-------------------
Not sure what you did on the graph paper.

Hi
Find the equation of the line with m=1/2 and passing through (10,3).
Using the standard slope-intercept form for an equation of a line y = mx + b
where m is the slope and b the y-intercept.
y = (1/2)x + b | using Pt (10,3) to solve for b
3 = 5 + b
-2 = b
y = (1/2)x -2
