Question

Find the slope of the line graphed below.

Answer 1

Have you determined the value of the coordinates highlighted in red?

Answer 2

one is -4,-2 and the other is 1,-5

Answer 3

Yes, now recall that the slope between the points \(\large (x_1,y_1)\) and \(\large (x_2,y_2)\) is given by the formula \(\large m=\dfrac{y_2-y_1}{x_2-x_1}\). Plug in the value of the points you found into this equation and simplify.

Can you take things from here? :-)

Answer 4

okay so we have -5-1 and -2- -4 so when i do that is it supposed to be -5-1 and -2-4 since the minus is like a negative in the second x2-x1? if that makes sense

Answer 5

Careful; note that a point is of the form (x,y). So (-4,-2) means x=-4 when y=-2 and (1,-5) means x=1 when y=-5. So when you plug the points into the formula, it should look something like this: \(m=\dfrac{(-5)-(-2)}{(1) - (-4)}=\ldots\)

Does this make sense? :-)

Answer 6

oh my goodness i am so sorry lol with the points ._. my writing is off today :( but yes it makes sense :)

Answer 7

the slope is gonna be -3/5 @ChristopherToni

Answer 8

Yes, that's correct. :-)

Answer 9

thanks very much :)
