$x-intercept = a = - 9, y-intercept = b = - \frac{9}{4}$ $color(brown)("x-intercept " = a = -9, " y-intercept " = b = -9/4$

$- x - 4 y = 9$ $-x -4y = 9$

$\frac{x}{- 9} + (- \frac{4}{9}) y = 1$ $x / -9 + (-4/9) y = 1$

$\frac{x}{- 9} + \frac{y}{- \frac{9}{4}} = 1$ $x / (-9) + y / (-9/4) = 1$

It's in the intercept form $\frac{x}{a} + \frac{y}{b} = 1$ $x / a + y / b = 1$

$:. color(brown)("x-intercept " = a = -9, " y-intercept " = b = -9/4$

What are the intercepts of -x-4y=9−x−4y=9-x-4y=9?
