Answer:
Infinity
Explanation:
Slope or gradient is given as the ratio of change of y axis in respect to change in x axis. Therefore,
m=∆y÷∆x
Where ∆y in given by y2-y1 and ∆x is equal to x2-x1
Taking point 1 to be (-7, -5) while point 2 is (-7, -7) then
∆y=-7--5=-2
∆x=-7--7=0
Therefore, the gradient will be -2÷0
Any number divided by zero is infinite. Therefore, the slope of these two points is infinite.
