Transcript text: Find the $x$ - and $y$-intercepts of the graph of the linear equation $-6 x+9 y=-18$
The $x$-intercept is $\square$ .
The $y$-intercept is $\square$ .
Solution
Solution Steps
Step 1: Find the \(x\)-intercept
To find the \(x\)-intercept, set \(y = 0\) in the equation and solve for \(x\):
\[
-6x + 9(0) = -18
\]
\[
-6x = -18
\]
\[
x = \frac{-18}{-6} = 3
\]
The \(x\)-intercept is \(x = 3\).
Step 2: Find the \(y\)-intercept
To find the \(y\)-intercept, set \(x = 0\) in the equation and solve for \(y\):
\[
-6(0) + 9y = -18
\]
\[
9y = -18
\]
\[
y = \frac{-18}{9} = -2
\]
The \(y\)-intercept is \(y = -2\).
