Answer:
The slope is 3
Hence the x-coordinate of the x- intercept is 2
Hence the y-coordinate of the y- intercept is -6
Explanation:
We are to first write the statement six less than triple some quantity as an expression:
let the quantity be x
Triple the quantity to have 3x
six less than triple some quantity will be expressed 3x - 6
The required function is f(x) = 3x - 6
This is in standard form of equation of a line y = mx+c
m is the slope
c is the y-intercept
Comparing 3x - 6 with mx+c
3x = mx
3 = m
m = 3
The slope is 3
x intercept occurs at when f(x) = 0
Substitute into f(x) = 3x-6
0 = 3x-6
-3x = -6
x = 2
Hence the x-coordinate of the x- intercept is 2
y intercept occurs at when x = 0
Substitute into f(x) = 3x-6
f(x) = 3(0)-6
f(x) = -6
Hence the y-coordinate of the y- intercept is -6
