Pls help me calculate the slope of the line that passes through (3,2) and (-7,4) in a fraction

-1/5

Step-by-step explanation:

slope can be found with the equation found in the image.

assign each coordinate with the according variable

x1 = 3       x2 = -7    y1 = 2    y2 = 4

and input the values accordingly.

4 - 2 / -7 - 3    PEMDAS (order of operations)

= 2/ -10           Simplify

= 1/ -5        

=-1/5

ratio is 2 : 9

the answer is three

13.5 : 3

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
