Answer:
y = 2x -5
Step-by-step explanation:
Given points: (0,-5) (1,-3)
(x1, y1) = (0,-5)
(x2, y2) = (1,-3)
Calculate the slope:
m = (y2 - y1)/(x2 - x1)
m = [-3 - (-5)] / [1 - 0]
m = (-3 + 5) / 1
m = 2/1 = 2
Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.
Therefore, the linear equation is: y = 2x -5

First find the side EC by setting up ratio. use pythagorean theorem to find the hypotenuse side.
If you increased 5 to 10, then I would have doubled the number 5 and this is a 100% increases.
If you increased 5 to 7.5, then this is 50% increase, because 50% of 5 is 2.5 and 5 + 2.5 = 7.5
If you increased 5 to 6, then this is a 20% increase,because 5 + 1 = 6 and 1 is 20% of 5
If you increased 5 to 7, then this is a 40% increase,because 5 increased by 2, 5 + 2 = 7, and 2/5 = 40%
If you increased 5 to x, then 5 was increased by x/5×100%
For example 5 to 9 is a4/5×100%=80% increase
So here 5 increases by 8, 5 + 3 = 8, thus the percentage increase is3/5×100%=0.006
