Can someone help me find the slope-intercept equation of the line passing through (2, 1) with a slope of M=3? Thanks!
the equation of a line is $\displaystyle y=mx+b$
$\displaystyle m$ is the slope.
you have $\displaystyle m=3.$
$\displaystyle y=3x+b.$
the line is passing through $\displaystyle (2,1)$
$\displaystyle b=y-3x=1-3\times2=-5$
therefore,
$\displaystyle y=3x-5$
it seems i'm late
Once again, jay1, you have posted a question with no evidence of trying yourself. You learn mathematics by doing, not by seeing some one else's solution. You do understand that there will be no one to give you the answer on exams, don't you?
