As the graph is basically y = 2x then <span>all the answer with a higher slope are meant to be equations that represtn relationship B. So the answers will be the second one: y=2.2x and the fourth one y= 3x</span>
Answer:
the 3rd one
Step-by-step explanation:
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using rise/run (y2 - y1) / (x2 - x1)
Plug in the points:
(36 - 21) / (15 - 10)
15/5
= 3
Next, plug the slope and a point into the equation y = mx + b to find b (y-int)
y = mx + b
21 = 3(10) + b
21 = 30 + b
-9 = b
Then, plug this into the equation, as well as the slope:
y = 3x - 9
Answer:
y = 1 x = 3
the +1 at the end of the equation is the y intercept while the number with the x is the slope, since the slope is -1/3 take it as if it was rise/run. In other words since the rise is -1 you are going down 1 unit and the run is 3 you are going 3 units to the right & that's the path its going to be taking. So that makes the line cross the x axis at (0,3)
