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
