Answer:
Step-by-step explanation:
To make things easier, let's first find the equation in slope-intercept form ( where m is the slope and b is the y-intercept.
1. Find the slope:
2. Find the y-intercept by plugging in (-1,1) into the equation
so = 4
3. Therefore the equation of the line in slope-intercept form is
4. To convert slope-intercept form into standard form, let's move the 3x over to the other side and divide by -1 to get rid of the negative.
Our result is .
Hope this helps :)
