#y=2x+1# using the point-slope formula

First, we write the point-slope formula, which is:

#y-y_"1" = m(x-x_"1")#

Now, we plug in the numbers, using 2 as #m# (slope), 3 for #x_"1"#(given x value), and 7 for #y_"1"# (given y value), then simplify.

#y-y_"1" = m(x-x_"1")#
=> #y-7 = 2(x-3)#
=> #y-7 = 2x-6#
=> #y=2x+1#
