Do you know how to find the slope between 2 points?

know the formula to find slope ?

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

so what slope did u get ?

I don't understand slope can you explain how i am supposed to set up the equation and then i could solve it

First point , (0,-10) compare it with (x1,y1)
u get x1=0, y1=-10
in same way find x2 and y2
and put all these 4 values in the formula i gave you to find slope =m

so would it be 0,-4/-10,0 for the equation?

1
the numerator has y-values

so in the numerator, its -10-0
got this ?
what will be in the denominator then ?
kenyababii123

1
the denominator would be -4-0 ?

i meant 0-4 ?

u missed a - *minus* sign
\(\huge 0-(-4)= 0+4=? \)

1
one minus sign comes from formula and one from the fact that the co-ordinate itself is negative , its -4

so would the equation be -10-0/0+4
hartnn

1
yes! correct :)
m=(-10-0)/(0+4)
hartnn

so m= ?

hold on im working out the problem now

so the answer would be -5/2
