first you have your slope or m which is 4
so your equation so far is
[tex]y = 4x + b[/tex]
to find b you use the point that was given which is (1,3), you substitute that in the equation which gives you
[tex]3 = 4(1) + b[/tex]
solve this equation which is

Let’s first know what y=mx+b is.


M= slope

B=y-intercept


Since the problem gives us the slope, we can add it in already, which helps us a lot.


y=4x+b


This problem gives us a coordinate. We can substitute the numbers with the values.

3=4(1)+b

3=4+b

-b=4-3

-b=1

b=-1


Now that we have the y-intercept, we now have the hard parts done and now all we do is put it together.


Answer: y=4x-1


To see if it is correct, we can substitute numbers in (like the coordinate) to see if it was right.

3=4-1

3=3


There is your answer!
