Answer:

slope = 3
y-intercept = - 5

Explanation:

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

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

The advantage to having the equation in this form is that m and b can be extracted 'easily'

#y=3x-5" is in this form"#

and by comparison with the slope-intercept equation.

slope = 3 and y-intercept = - 5
