the x-intercept of a line is -5 and the y-intercept of the line is -2. what is the equation of the line?
A. y= -5/2x-5
B. y= 2/5x+2
C. y= 5/2x-2
D. y= -2/5x-2

use the intercept form of line :-
\(\large \frac{x}{a} + \frac{y}{b} = 1\)
ganeshie8 (ganeshie8):
and simplify it to y = mx+b form
ganeshie8 (ganeshie8):
in above equation/s,
a = x intercept
b = y intercept

I use to know how to do this but im so confused now
ganeshie8 (ganeshie8):
its okay, let me show u how to simplify

alright thank you
ganeshie8 (ganeshie8):
\(\large \frac{x}{-5} + \frac{y}{-2} = 1\)
add x/5 both sides
\(\large \frac{y}{-2} = \frac{x}{5} + 1\)
multiply -2 thru out
\(\large y = \frac{-2x}{5} - 2\)
ganeshie8 (ganeshie8):
see if that makes some sense
OpenStudy (anonymous):
so your adding x/5 to the other side oooh I see now because multiplying -2 to them
OpenStudy (anonymous):
that made so much sense thank you
