Find the equation of the line joining the points (4, 9) and (-1, 0)
Fed [463]

The equation of the line joining the points (4, 9) and (-1, 0) is y = 9/5 x + 9/5

<h3>How to find the equation of a line?</h3>

The formula for calculating the equation of a line is expressed as:

y = mx + b

m is the slope

b is the intercept

Determine the slope:

Slope = 0-9/-1-4
Slope = -9/-5
Slope = 9/5

Determine the y-intecept

0 = 9/5(-1) + b

b = 9/5
Hence the equation of the line is y = 9/5 x + 9/5

shutvik [7]

Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Note that 24 hours = 1 day

In a parallelogram, one angle is 9 times the size of another. Find the measures of the angles.
Pavlova-9 [17]
In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.

You can label one pair of opposite angles with x and the other 9x. 

You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into 

20x=360

x=18 

Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162. 

The angles of the parallelogram is 18,18, 162 and 162. 

Note: you can check if this is right if all the angles add up to 360.
