# How do you graph y=-3^2-4x ?

May 28, 2017

$y$ is a straight line with slope $- 4$ and y-intercept of $- 9$

#### Explanation:

NB: The question is ambigious as it is not clear whether $y = - \left({3}^{2}\right) - 4 x$ or $y = {\left(- 3\right)}^{2} - 4 x$.
I will assume the first case as the second would not require the negative sign.

Thus $y = - 9 - 4 x$

The equation of a straight line in slope $\left(m\right)$ and intercept $\left(c\right)$ form is $y = m x + c$

Hence, in this example, $y$ is a straight line with slope $- 4$ and y-intercept of $- 9$

As can be seen on the graph of $y$ below.
