Step-by-step explanation:
gradient(m)=change in y/change in x
=5-1/-9-(-4)
=4/-9+4
=4/-5
equation now
y-y1=m(x-x1)
y-1=4/-5[x-(-4)]
y=4/-5(x+4)+1
y=-4/5x-16/5+1
y=-4/5x-21/5
Answer:
Step-by-step explanation:
First, put ur equation in y = mx + b form
y - 6x - 9 = 0
y = 6x + 9
now, to put it in function notation, sub in f(x) for y
f(x) = 6x + 9 <== function notation
The student mixed the letters. If you swicth the order of the letters then the equation would be true. y=4x. So if you plug in all the numbers into the equation you get the correct value for why. For example 4×2=8, 4×4=16, and so on.
6x^2...degree 2
18x^3 5ab - 6y...degree 6
8a - 5...degree 1
4x^3y + 3x^2 - xy - 4.....degree 8
