Thank you Christina.. I am taking Algebra online...something I would never recommend....How would I write the equation of the line passing through (6,37) and (1,12)?
the most common way is to use y=mx + b
where m is the slope and b is the yintercept
so the first thing you have to do is to find the slope, I will assume you know how to do that
m=(1237)/(16)
=25/5
=5
Now pick the simpler looking of your two points, say (1,12) and substitute the x, the y and the m in your equation.
12 = 5(1) + b
so b =7 and your equation is
y = 5x+7
to test if this is right, use the point that was not used and replace its values in the equation.
Left side = 37
Right side = 5(6)+7 = 37
so we have the right equation
