Find the slope and the y-intercept: x+ y = 9

Question

anonymous · Answer

$$\large y=\color{red}mx+\color{blue}b$$m is the slope
b is the y-intercept

Get the equation is this form

anonymous · Answer

So, we can easily answer this question by changing its form into y = mx + b.  In this form, m is the slope and b is the y-intercept.

x + y = 9
y = -x + 9

So, the slope is -1, and the y-intercept is 9

phi · Answer

you should have tried this one on your own, because all you have to do is add -x to both sides to change the equation into slope intercept form
