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

    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.

    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?

    the numerator has y-values

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

    the denominator would be -4-0 ?

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

    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

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