Answer:

y = 5x - 7

Step-by-step explanation:

The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the slope m = 5. Therefore we have the equation

[tex]y=5x+b[/tex]

Put the coordinates of a given point (2, 3) to the equation:

x = 2, y = 3

[tex]3=5(2)+b[/tex]

[tex]3=10+b[/tex]            subtract 10 from both sides

[tex]-7=b\to b=-7[/tex]

Finally:

[tex]y=5x-7[/tex]
