Answer:
below..
Step-by-step explanation:
- slope = (y - y1)/(x-x1) = (6 - 3 )/(1-0) = 3 is the slope/ gradient
- equation of the line = y -3 = 3(x - 0) => y = 3x + 3
Answer:
yes: each input has only one output
I see you accidentally pasted the expression 2(4x-3)+3x-1 twice, so
expand 2(4x-3) to get
2(4x)+2(-3)=8x-6
now we have
8x-6+3x-1
regrouping we get
8x+3x-6-1
adding like terms
11x-7
A is 11x-4, not 11x-7, wrong
B is wrong
C. hmm, 6x-6+5x-1=11x-7, yep
D is the same, we can see
C and D are correct
