Question

Find the slope-intercept form for the line satisfying the following conditions.
x-intercept=2, y intercept =4/5

Answer 1

Why is it negative ?

Answer 2

Shouldn't it just be y= 4/15+ 4/5

Answer 3

the line would be \(\frac{x}{2}+\frac{y}{\frac{4}{5}} =1\)
rearrange to point intercept form. it is neg. gradient

Answer 4

Ok so what if its x intercept is 3 and y is 1/3

Answer 5

the line would be \(\frac{x}{3} +\frac{y}{\frac{1}{3}} =1\)
rearrange again. the line has a neg gradient.
I believe you've noticed the correlation?

Answer 6

So y= -1/9+1/3

Answer 7

y= -x/9+1/3
yup. u've got it.

Answer 8

Cool thanx

Answer 9

you're welcome :)
