What can I do with a coordinations and the slope

Mathematics

You can plot a linear equation, if you are given the coordinates and the slope for THE SAME line.

Assuming you have those, the first step is to find the y-intercept.

That is done by replacing x and y in the general formula by their coordinated counterparts, and replacing m by the slope that is given to you.

Let's assume the coordinates you are given are (5,10), and the slope you are given is 1.

By substituting into the general formula...

y=mx+c\\(10)=(1)(5)+c\\10=5+c\\10-5=c\\c=5

...we can see that it is possible to find the y-intercept (c).

Knowing the y-intercept, it is possible to plot the line and solve any question.

I'll leave a picture of the example used above when graphed.

AB, CD and EF are straight lines. <br> AB is parallel to CD.<br> work out the size of angle y.
Yuri [45]

Answer:

y = 108°

Step-by-step explanation:

Since, line AB is parallel to line CD,

By the definition of corresponding angles,

m∠FPB = m∠FQD

(2x + 16)° = (3x - 12)°

3x - 2x = 16 + 12

x = 28

(3x - 12) = 3(28) - 12

             = 72°

m∠FQD + m∠EQD = 180° [Linear pair of angles]

72° + y = 180°

y = 180 - 72

y = 108°

At a swim meet, it took Deborah 40.8 seconds to complete the 50 meter freestyle event. It took Robert 60.2 seconds to complete t
GarryVolchara [31]

Answer:

Emily's speed is the greatest, therefor she is the fastest at a speed of 1.78 m/s

Step-by-step explanation:

To determine who swam the fastest we need to calculate the speed for each swimmer;

Speed=Distance/time

Deborah covered a distance of 50 meters in 40.8 seconds,

Deborah's speed=(Deborah's distance/Time)=(50/40.8)=1.23 meters per second

Robert covered a distance of 100 meters in 60.2 seconds,

Robert's speed=(Robert's distance/Time)=(100/60.2)=1.66 meters per second

Emily covered a distance of 200 meters in 112.4 seconds,

Emily's speed=(Emily's distance/Time)=(200/112.4)=1.78 meters per second

From the speeds for each we can conclude that;

Emily's speed(1.78 m/s)>Robert's speed(1.66 m/s)>Deborah's speed(1.23 m/s)

Emily's speed is the greatest, therefor she is the fastest at a speed of 1.78 m/s
