Can someone please help me to answer the following question? The question below has four choices, but only one correct answer. Could you please help me with the correct answer for this question? Thank you in advance.

Question # 1. Find the slope of the line passing through the points
(-3, -10) and (4, 5).

These are the four choices:

-15/7

-7/15

15/7

7/15

  • Math - ,

    This is the formula for finding the slope of a line.

    m is the variable used for the slope


    m=(y2-y1)/(x2-x1)

    m=[(5-(-10)]/(-3-4)

    m=(-15)/(-7)

    m=15/7 Becose ratio of two negative nubers is positive number

  • Math - ,

    My mistake :

    [(5-(-10)]=5+10=15

    m=15/(-7)=(-15)/7

  • Math - ,

    the points
    (-3, -10) and (4, 5).

    m=(y2-y1)/(x2-x1)

    m=[5-(-10)]/[4-(-3)]
    m=15/7
