Answer:

slope: -1/6

Step-by-step explanation:

to find the slope of a line we can use the formula (y2-y1)/(x2-x1)

this means ththe second y subtracted by the first year divided by the second x subtracted by the first x

when plugged in you get (10-8)/(-7-5)

when simplified it becomes 2/-12 and then -1/6
