Question

How do you graph using slope and intercept of `3x + 2y = 21`?

Answer 1

`m= ((-3)/2)`
`x=7`
`y=10.5`

Explanation:

• `x` - Intercept `->` when `y=0`
• `y` - Intercept `->` when `x=0`
• For the slope re-arrange the equation to the for `y=mx+b`

SLOPE:

`y=(-3x+21)/2`

`y=((-3)/2)x+10.5`

So your `color(orange)(m= ((-3)/2))`

X-INTERCEPT:

`3x=21`

`color(orange)(x=7)`

Y-INTERCEPT:

`2y=21`

`color(orange)(y=10.5)`
