Find the equation of the line with x-intercept 3 and y-intercept -7.

Sagot :

x/a + y/b =1
x/3 + y/-7 = 1
(x/3 + y/-7 = 1)(21)
7x - 3y = 21

The intercept form to find the equation of the line is:
[tex]\frac{x}{a}+\frac{y}{b}=1[/tex]
[tex]\frac{x}{3}+\frac{y}{-7}=1[/tex]
Multiply both sides by the LCD of a and b which is 21
7x-3y=21
The equation is 7x-3y=21. Hope this helps =)
