Question

write an equation of the line : in attachment

Answer 1

So, you are given two points, right?

Answer 2

(0,-3) (-8,-5)

Answer 3

Right. You can now use the two-point form to solve this one. You want what a two-point form is?

Answer 4

yes please

Answer 5

We can actually derive that from the point-slope form. It's almost the same thing, actually. Point slope form is \[y-y _{1} = m (x-x _{1})\] and we know that m = \[\frac{ y _{2} - y _{1} }{ x _{2}-x _{1} }\] and as we substitute that to m. we will have
\[y-y _{1} = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } (x-x _{1})\]
Hence, what will be the equation?

Answer 6

y+3=1/4x

Answer 7

Just simplify it. :)
