Answer:
slope is -3 and y intercept is 1
Step-by-step explanation:
The slope is the difference between two points on a graph. The y intersept is where the line touches the y axis. That majes the y intersept 1.
3/5 and 6/8 are not proportional as even though 3 goes into 6 evenly, 5 does not go into 8 evenly so that makes it disproportional.
You need to use the "mean". -4 + -3 + -5= -12 ÷ by 3 = -4°. the answer is -4
