Gawsh Im stumped and I need help fast!
I need to know the slope and the y-intercept of the following equations:
y= 3x + 5
y= -6x + 3
y= -3/4x - 1
y= 5/-4x
y= 7 + 4x
y= -x/5 + 6
(Oh yah the slashes are for fractions!)
1) $\displaystyle y = 3x + 5$
This equation is of the form $\displaystyle y = mx + b$, where $\displaystyle m$ is the slope and $\displaystyle b$ is the $\displaystyle y$-intercept.
Therefore, the slope is $\displaystyle 3$ and the $\displaystyle y$-intercept is $\displaystyle 5$.
2) $\displaystyle y= -6x + 3$
Same thing here. Slope is $\displaystyle -6$ and $\displaystyle y$-intercept is $\displaystyle 3$.
3) $\displaystyle y= -3/4x - 1$
Once again, same format. Slope is $\displaystyle -3/4$ and $\displaystyle y$-intercept is $\displaystyle -1$.
4) $\displaystyle y= 5/-4x$
Is this what you mean? $\displaystyle y = \frac {-5}{4}x$
If so, the slope is $\displaystyle \frac {-5}{4}$ and the $\displaystyle y$-intercept is $\displaystyle 0$.
Basically the same thing for each one.
