y = 4/5x + 5

Explanation:

The slope intercept for is: color(red)(y = mx + b)
Where m is the slope and b is the y-intercept.

We must solve the equation given for y:

y - 1 = 4/5x + 4/5*5

y - 1 = 4/5x + 4/cancel(5)*cancel(5)

y - 1 = 4/5x + 4

y - 1 + 1 = 4/5x + 4 + 1

y - 0 = 4/5x + 5

y = 4/5x + 5

y=4/5x+5

Explanation:

The equation of a line in color(blue)"slope-intercept form" is.

color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))
where m represents the slope and b, the y-intercept.

Begin with distributing the bracket.
