slope
y-intercept = 20
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 is the slope and b, the y-intercept.The advantage of having the line in this form is that m and b can be extracted 'easily'
The equation
#y=-2/3x+20" is in this form"# hence slope
#=-2/3" and y-intercept"=20#
