What is the equation of the line that has a slope of 2 and passes through the point (8,3)?

Answer 1

The equation should be in the form:

y=kx+b.

Here we have the slope, k=2. So the equation becomes

y=2x+b.

Now the only thing is left to be done, to find the value of b.

The line passes through the point (8,3), This means that when x=8, y=3

3=2*8+b.

From here b=-13 and the equation of the line is

y=2x-13
