Equivalent ratios both the numerator and denominator by the same value, e.g.
27/30
18/20
First, find the slope between the two points.
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation.
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case.
y= 1/3x or in other words y= x/3
Answer:
Y = 1/27x
Step-by-step explanation:
In order to find the inverse we switch places with x and y to get x = y27. In order to even out the equation, we divide both sides by 27 to get our answer. The answer would be y = x/27 or y = (1/27)x.
Apologies if I'm incorrect.
To reflect a function across the x axis, we want to turn all the x values that were once positive negative and vice versa. That means we want f(-x), which is:
