Question 68146
What is the slope, x-intercept, and y-intercept of the following line?
3x + 4y = 9
The slope intercept form of a line is: {{{highlight(y=mx+b)}}} where m=slope and (0,b)=y-intercept.
{{{3x-3x+4y=-3x+9}}}
{{{4y=-3x+9}}}
{{{4y/4=-3x/4+9/4}}}
{{{y=(-3/4)x+9/4}}}
{{{y=highlight(-3/4)x+9/4}}} the slope, m=-3/4
{{{y=(-3/4)x+highlight(9/4)}}} the y-intercept, (0,b)=(0,9/4)
Happy Calculating!!!
