We can see that the slope(m) equals 4 and the y-intercept is in the point (0, 1).
***
When you have a linear function of the form:
[tex]y=mx+b[/tex]You will have that m represent the slope and b will represent the y-intercept, in our case the function is:
[tex]y=4x+1[/tex]We can see that the slope(m) is then 4 and the y-intercept(b) is 1.
