Question

I’m sorry I don’t understand these

Answer 1

1)positive slope

2) 6

3) w = 12t

4)
`slope = (2)/(-5)`

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
`k = (24)/(4) = 6`.

3) The earning rate is given by $12 per hour. If the number of working hours are t, then the total earnings are
`w= (12)(t)`.

4)The slope is given by ,
`m = (y2-y1)/(x2-x1)`, where (x1,y1) and (x2,y2) are endpoints. Thus, here above the slope is given by,

`m = (3-1)/(1-6) = (2)/(-5)`
