Hi there!
To write a equation of a graph, we must follow the formula y = mx + b, where m is the slope and b is the y-intercept. In this scenario, we can utilize this formula to get our answer. First, let's take a look at the y-intercept. To find this, we need to take a look at the graph. We can see that the line crosses the y-axis at the point (0,250). Hence, 250 will be our y-intercept. Now, we can move on to the slope. This can be found by first taking two points from our graph. Here are the two points I'll be using - (0,250)(2,200). Now, use the slope formula, which goes as m = y₂ - y₁ / x₂ - x₁. All we have to do is plug in the respective values from the coordinate points. We get -
m = 200 - 250 / 2 - 0
m = -50 / 2
m = -25
Using the information we have derived, we can construct the equation y = -25x + 250. Usually, the answer should be written in standard form, which goes as Ax + By = C, where A, B, and C are numbers. Therefore, to derive y = -25x + 250 into standard format, we must add 25x to both sides. This gives us y + 25x = 250. Hope this helped and have a marvelous day!
Answer:
18 kmh
Step-by-step explanation:
Given: Speed of cyclist is 9 km/h more than skater´s speed.
Distance covered at the given time by cyclist is 45 km and by skater is 30 km.
Let´s assume the speed of skater be "x"
∴ Speed of cyclist will be 
Remember; time= 
We know the time taken by both cyclist and skater are same.
∴ we can form an equation to find the speed of skater.
Time taken by cyclist= time taken by skater
⇒ 
Multiplying both side by 
⇒ 
Using distributive property of multiplication
⇒
Subtracting both side by 30x
⇒
Dividing both side by 15
⇒
∴
Hence, speed of the skater is 18 kmh
5/3 means (5 over 3 since I can't do fractions on this)
5/3-3/3=___
5-3=2 first you do the numerators
You keep the denominator the same since both denominators are 3
Then you put it together and get 2/3 and since 2/3 can't be reduced, 2/3 is the answer
