Answer:
1)positive slope
2) 6
3) w = 12t
4)
Step-by-step explanation:
1) The slope of line is given by tan(∅), Where ∅ is the angle of line with positive x axis. Here The value of ∅ is between 0 and 90 degrees, so tan(∅) is positive, which means slope is positive.
2) It is given that y=24 and x=4, inserting in the given equation, we get .
3) The earning rate is given by $12 per hour. If the number of working hours are t, then the total earnings are .
4)The slope is given by , , where (x1,y1) and (x2,y2) are endpoints. Thus, here above the slope is given by,
