Question

Whats the slope and y intercept of 21x+45y=-6

Answer 1

The line's equation is:

`21x+45y=-6​`

To get slope and y-intercept, we have to re arrange this into slope intercept form, that is:

y = mx + b

Where

m is the slope

b is the y-intercept

Let's do this:

`\begin{gathered} 21x+45y=-6​ \\ 45y=-21x-6 \\ y=-(21x)/(45)-(6)/(45) \\ y=-(21)/(45)x-(6)/(45) \end{gathered}`

So,

The slope is -21/45

y intercept is -6/45
