Question 119885: find the slope and y-intercept of y= -2/3x+20
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! The slope-intercept form of an equation is:
.
y = mx + b
.
in which m, the multiplier of x, is the slope and b, a constant, is the y-intercept.
.
The equation you are given is y = (-2/3)x + 20 and you can see by inspection that this equation
is in the slope-intercept form. By comparing this equation with the slope-intercept
form, you can see that the multiplier of the x is -2/3 so the slope of the line of the given
equation is -2/3. You can also see by this comparison that the constant term is +20, and
so the y-intercept is +20.
.
So the answer to you problem is slope = -2/3 and y-intercept = +20 ... both of which you
can immediately identify by inspection.
.
Hope this helps you to understand the problem.
