AWS Managemer Consider the equation 4x – 3y = 9. Write the equation in slope-intercept form, y = mx + b, and then determine the slope. The slope i I don't 4/3 -(4/3) -3 4

Answer 1

Given the equation :

$4x-3y=9$

we need to write the given equation in slope - intercept form

The general slope intercept form is :

$y=m\cdot x+b$

So, we need to convert the 4x - 3y = 9 to the previous form

So, solve the given equation for y ( make y alone on the left side )

So,

$4x-3y=9$

Subtract (4x) from both sides

$\begin{gathered} 4x-3y-4x=9-4x \\ \\ -3y=-4x+9 \end{gathered}$

Divide all terms by -3

$\begin{gathered} \frac{-3y}{-3}=\frac{-4x}{-3}+\frac{9}{-3} \\ \\ y=\frac{4}{3}x-3 \end{gathered}$

So, the slope will be the coefficient of x = 4/3

Slope = 4/3
