Question

find the x-intercept of 4x+5y=25

Answer 1

one little note is that there is a not used much form called the intercept form; and all you do is divide it all by that 25 to get:

\[\frac{4x}{25}+\frac{5y}{25}=1\]
\[\frac{x}{25/4}+\frac{y}{25/5}=1\]
\[\frac{x}{25/4}+\frac{y}{5}=1\]

Answer 2

now it easy to tell that when x = 0; y = 5

and when y=0, x=25/4

Answer 3

yint (0,5)
xint(25/4 ,0)

Answer 4

What are the y and x intercepts for x+5y=25?

Answer 5

x +5y = 25 ; /25

x/25 +5y/25 = 1

x/25 + y/5 = 1 ; when x=0, y=5; yint = (0,5)

x/25 + y/5 = 1 ; when y=0, x=25; xint = (25,0)
