A parent sine function y=a (x - h) + k ca be defined as
a is the amplitude.
h is the horizontal shift or the phase shift(shift to the left or right)
k is the vertical shift(shift up or down)
Y - 3 = 5(x - 4)
y - 3 = 5x - 20
y = 5x - 20 + 3 = 5x - 17
=> slope = 5
For perpendicular line, m2 = -1/m1 = -1/5
Answer:
Using substitution method
First make y in equation 1 the subject of formula
Y=4x-2
Sub in equation 2
2(4x-2)-8x=4
8x-4-8=4
8x=4+12
8x=16
X=2
Sub in any of equation to get y
Step-by-step explanation:
Y =4(2)-2=6
Answer:
A={5,1,-7}
Step-by-step explanation:
domain = x
choose domain {-2,0,4} to 2x+y=1
range = y
range is
2(-2)+y =1 ,y =5
2(0)+y=1, y= 1
2(4)+ y=1, y=-7
range = {5,1,-7}
