Question

What are the intercepts of `7x+16y=4`?

Answer 1

`color(indigo)("x-intercept " = a = 4/7, " y-intercept " = b = 1/4`

Explanation:

`7x + 16y = 4`

Intercept form of standard equation is `x / a + y / b = 1`

`(7/4)x + (16/4) y = 1`

`x / (4/7) + y / (1/4) = 1`

`color(indigo)("x-intercept " = a = 4/7, " y-intercept " = b = 1/4`
