Answer:
The slope of this equation should be -2/3
Step-by-step explanation:
Label the points with x1,y1 and x2,y2
(1,42) (4,40)
x1,y1 x2,y2
Then put them into the slope formula.
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
m=[tex]\frac{40-42}{4-1}[/tex]
Then once you solve it, the answer should come out to -2/3
