Question

A line with a slope of 1 passes through the point (7,4). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

solution

For this case the slope intercept formula is given by:

y = mx +b

The slope is given m=1

And we can use the point x= 7 and y=4 and we have this:

4 = 1*7 +b

And solving for b we got:

b= 4 -7 =-3

And then the solution would be:

y = x -3
