Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

please help i dont understand algebra at all. dont tell me to do my own work. i need an answer and maybe an explanation thats very simple so i know what this means

Answer 1

x f(x)
−1 −3
0 0
1 3

based on the table above. f(x) = 3x

g(x) = 7x + 2

Part A:
Function in form of y = mx + c where m is the slope and c is the y-intercept.
You can find the slope by looking at m, the coefficient of x-term.

slope of f(x) is 3
slope of g(x) is 7

Part B
You can find the y-intercept by looking at c in y = mx + c

y-intercept of f(x) is 0
y-intercept of g(x) is 2

Answer 2

remember slope formula is y=mx+b m is the slope b is the y intercept

Part a-1+5/0+1 = 4/1 that just equals 4 slope of g(X) is 4

part b y = 4x + b -1 = 4(0) + b -1 = b so y = 4x - 1

the function g(x) has a bigger y intercept (or where it crosses y on a graph) y intercept of g(x) is 3 and the y intercept of f(x) is -1

This really helps if you graph it
