Question

What is a possible equation for a function with an x-intercept of (-5,0) and a y-intercept of (0,3)?

Answer 1

The equation of a straight line is

-3 x+5 y=15

Explanation:

Given x - intercept of (-5,0) and y- intercept is (0,3)

here (-5,0 ) point lie on x- axis and (0,3) this point lie on y- axis

we know that the x- intercept 'a' and y- intercept 'b' formula is

`(x)/(a) +(y)/(b) = 1`

so given x - intercept a =-5 and y- intercept is b= 3

now the straight line equation is
`(x)/(-5) +(y)/(3) =1`

now simplify
`(-3 x+5 y)/(15) =1`

`-3 x+5 y=15`
