Write the equation of a line that goes through (5,3) and (2,7)
I found the slope of the line to be -4/3
Then, I substituted one of the points in for x and y to be:
y = -4/3x + b
3 = -4/3(5) + b
3 = -20/3 + b
3 + 20/3 = b
This is where I am stuck == do I have to find the common denominator, so I end up with 29/3 as my b?
So then my equation is y = -4/3x + 29/3?
