Question

Identify the x and y intercepts for the equation 4x + 3y = 12

Answer 1

To solve for the x-intercept, set y=0
To solve for the y-intercept, set x=0

Answer 2

so now what ?

Answer 3

4x+3(0)=12 4(0)+3y=12
Simplify and the answers and will be your x and y-intercepts

Answer 4

Even cooler, just divide by 12.

\(\dfrac{x}{3} + \dfrac{y}{4} = 1\)

And the intercepts are just staring at you.

Answer 5

im so lost

Answer 6

?

Answer 7

That form I showed you is called the "Intercept Form". Just read the denominators.

x intercept (3,0)
y intercept (0,4)

That's it.
