slope=-2/3=−23
y-intercept = 20

Explanation:

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