Given the equation: [tex]2x + 3y = 9[/tex]

1. Slope-intercept form is: [tex]y = -\frac{2}{3}x + 3[/tex]
2. The slope of the line is: [tex]-\frac{2}{3}[/tex]
3. The [tex]y[/tex]-intercept is: [tex]3[/tex]



Answer :

To convert the given equation [tex]\( 2x + 3y = 9 \)[/tex] to the slope-intercept form, we need to solve for [tex]\( y \)[/tex] in terms of [tex]\( x \)[/tex].

1. Start with the given equation:
[tex]\[ 2x + 3y = 9 \][/tex]

2. Isolate [tex]\( y \)[/tex] by moving the [tex]\( 2x \)[/tex] term to the other side of the equation:
[tex]\[ 3y = -2x + 9 \][/tex]

3. Divide every term by 3 to solve for [tex]\( y \)[/tex]:
[tex]\[ y = \frac{-2}{3}x + \frac{9}{3} \][/tex]

4. Simplify the constants:
[tex]\[ y = \frac{-2}{3}x + 3 \][/tex]

Now, the equation is in the slope-intercept form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] is the slope and [tex]\( b \)[/tex] is the y-intercept.

- The slope of the line [tex]\( m \)[/tex] is:
[tex]\[ -\frac{2}{3} \approx -0.6666666666666666 \][/tex]

- The y-intercept [tex]\( b \)[/tex] is:
[tex]\[ 3 \][/tex]

So, the slope-intercept form of the equation is [tex]\( y = -\frac{2}{3}x + 3 \)[/tex].

- The slope of the line is:
[tex]\[ -\frac{2}{3} \approx -0.6666666666666666 \][/tex]

- The y-intercept is:
[tex]\[ 3 \][/tex]
