Answer:

y=-\frac{1}{2}x+3

Step-by-step explanation:

Let's write the equation of the line in slope-intercept form, y= mx +c.

  • m= slope
  • c= y-intercept

Since we are given the slope value, we can substitute it into m in the equation.

y=-\frac{1}{2}x+c

The question also tells us that this line passes through the point (6, 0). This means that (6, 0) has to satisfy the equation above, where c is an unknown value. The point (6, 0) means that when x= 6, y has a value of 0.

Substituting point (6, 0):

0=-\frac{1}{2}(6) +c

Solve for c:

0= -3 +c

c= 3

Substitute the value of c:

Thus, the equation of the line is \bf{y=-\frac{1}{2}x+3 }.

Do check out the following question for an example of writing equation of lines using the point-slope formula!

dexar [7]
7 spaces total
7 × 1cm = 7cm

6 box cars
6 × 7cm = 42cm

1 engine
1 × 12cm = 12cm

7cm + 42cm + 12 cm = 61cm

The train is 61cm long.

A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?
andre [41]

Answer:

A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?

Step-by-step explanation:

Mostly it's 1.25 hours </3 Since distance = rate times , or d = rt, then we have

t = d/r = 60 miles / 48 mph = 1.25 hours = 1 hour 15 minutes

either 1 hour 15 mins or 1hour and 25 mins.

Then multiply all the parts correctly.

-21 + 60 - 9

-21 + 60 = 39

-9
