Question

Please help with the slope problem...I don't need answers, I want to know how to solve it step by step. thank you...see the problem in attached file.

Answer 1

do you know the slope-intercept form of the equation of a line?
\(\Large y=mx+b?\)

Answer 2

no that's the point I want to know

Answer 3

so \(\Large y=mx+b\) is the slope-intercept form of the equation of a line, where \(m\) is the slope and \(b\) is the y-intercept

in your case, you are given the x-int (-5,0) and y-int (0,-2)
you already have the y-int, so just plug in the y-int to the equation
you will have \(\Large y=mx-2\)
so we just need the slope \(m\)

to find the slope we use the formula: rise/run
or simply \(\Large m= \frac{y_2-y_1}{x_2-x_1}\)
where \((x_1,y_1)\) and \((x_2,y_2)\) are the give points
substitute the points in the slope formula and solve for the slope
\(\Large m= \frac{-2-0}{0-(-5)}\)

you'll get??

Answer 4

after you get the slope, put it in the equation

Answer 5

I'll get \[m=-\frac{ 2 }{ 5 } or m=\frac{ 2 }{ 5 }\] with negative or positive? Or am I getting it wrong?

Answer 6

with the negative because 5 will be positive :)
so now put the value of m in the equation

Answer 7

\[y=-\frac{ 2 }{ 5} x - 2\] am I understanding correct?

Answer 8

yes, so far you're good ;p

Answer 9

thank you so much!! and do I follow the same steps on this one?

Answer 10

like a bit opposite

Answer 11

for this one, i think you need to simplify this whole equation until it will be in the form y=mx+b

try it, i'll check it if we got the same thing :))

Answer 12

okei :D

Answer 13

done?

Answer 14

almost um I got this but not sure if right \[y= -\frac{ 5 }{ 2 }\] so far but i don't know what to do in parenthesis

Answer 15

@Data_LG2 so did I do right? I think \[y=-\frac{ 5 }{ 2 } x-3\]

Answer 16

sorry late respond, i just ate my dinner

that looks right (^_^)

Answer 17

thank you!! (^_^)

Answer 18

no problem :)

did you understand it now?

Answer 19

Yes I do, that's what i like it best, people give answers but why do we need answers if we're not going to know how to solve it, once we know how to solve it'll be easier to know the answers in future (^_^)

Answer 20

good to hear that ^.^
everyone should be like you ;p
if you need anything just ask , see ya 'round!

Answer 21

haha thank you! and will do! (^_^) see ya!
