thank you so much! :3 heres a cookie!..okay theres no cookie, but help a sister out, please? :(
Hi again Sister Serena;
2x +3y + 6 = 0
I would prefer this equation to be in the format of...
y=mx+b
m=slope, the change in y, also known as rise, divided by the change in x, also known as run.
b=y-intercept, the value of y when x=0.
2x +3y + 6 = 0
Let's subtract (2x+6) from both sides...
-(2x+6)+2x+3y+6=0-(2x+6)
3y=-2x-6
Let's divide both sides by 3...
(3y)/3=(-2x-6)/3
y=(-2/3)x-2
The slope is -2/3 and the y-intercept is -2.
According to protocol, the slope is represented as -2/3 in that the negative sign is before the numerator. However, the field of mathematics has a problem. The negative sign should be before the 3, 2/-3, This is because as the line rises positively 2 units, it runs negatively to the left 3 units.
Draw your line beginning with (0,-2), then rise 2 and move to the left 3 to find the next point.
