what's the equation of the line?

OpenStudy (paxpolaris):

i can see the y-intercept is at (0,3) ... and the x-intercept is at (5,0) is that correct?

OpenStudy (paxpolaris):

then can you get me the equation of the line.

OpenStudy (anonymous):

for the intercept i would eter it as a fraction right? @PaxPolaris

*enter

OpenStudy (paxpolaris):

?

OpenStudy (anonymous):

I got it wrong when i filled out the boxes

OpenStudy (paxpolaris):

\[y= mx+b\] b is the y-intercept \(b=3\)

OpenStudy (paxpolaris):

m is the slope . since the line passes thru (5,0) and (0,3) m=?

OpenStudy (anonymous):

5?

OpenStudy (paxpolaris):

\[\Large m = { rise \over run} = {y_2 - y_1 \over x_2-x_1} = {0-3\over 5-0}=\color{green}{-\frac35}\]

OpenStudy (paxpolaris):

Since you are shading the region BELOW the solid line. the inequality is: \[\Large y \le -\frac35x+3\]
