Answer:
y = 5x - 39
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
Put the value of slope m = 5 and the coordinates of the given point (8, 1) to the equation of a line:
[tex]1=(5)(8)+b[/tex]
[tex]1=40+b[/tex] subtract 40 from both sides
[tex]-39=b\to b=-39[/tex]
Finally:
[tex]y=5x-39[/tex]
