Write the following equation in slope intercept : 4x + 3y = 9
2 answers:
Answer: y = -4/3x + 3
Step-by-step explanation: To write this equation in slope-intercept form which is more commonly referred to as y = mx + b form, we need to get y by itself on the left side of the equation by subtracting 4x from both sides to get 3y = -4x + 9.
Now we need to divide both sides by 3 in order to get <em>y</em> by itself.
This leaves us with .

Hi there! :)
4x + 5x + 12 = 6(x - 2)
Combine like terms and distribute the coefficient outside of the parenthesis:
9x + 12 = 6(x) + 6(-2)
9x + 12 = 6x - 12
Subtract 6x from both sides:
9x - 6x + 12 = 6x - 6x - 12
3x + 12 = -12
Subtract 12 from both sides:
3x + 12 - 12 = -12 - 12
3x = -24
Divide both sides by 3:
3x/3 = -24/3
x = -8.
So the -4x is the M and then 6 is the B. So m is the slope and B is the y-intercept. The 6 goes on the y axis and the -4 will be how the line looks. It’ll be rise (-4) over run (1).
