Determine the slope of each line

Plz help!!!

7/3

Step-by-step explanation:

To solve use:

(-1,5) and (-7,-9)

x1  y1       x2  y2

m=        *When multiplying or dividing a negative by a negative you get a positive*

Solve:

m= or -------->

Hope this helps!

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
