Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0, y)
Function A:
y-intercept = -2/3
Function B:
You can find the y-intercept by finding the slope-intercept form of the function, or you can look at the table and find a pattern. The pattern is: when x increases by 2, y decreases by 1. If you continue the pattern, when x = 0, y is -7.
So the y-intercept = -7.
The y-intercepts of both functions are negative
The y-intercept of two functions A and B are negative as per the slope-intercept form of a straight line.
What is the slope-intercept form of a straight line?
The slope-intercept form of a straight line is: y = mx + c, where 'm' is the slope and 'c' is y-intercept.
Given, two functions A and B.
Function A: [tex]y = (\frac{1}{4})x - \frac{2}{3}[/tex].
Therefore, the y-intercept of function A = -2/3.
Again, function B: x =2, y = -8; x = 4, y = -9;.....; x = 8, y = -11.
Therefore, we can assume based on the given table, x = 0, y = -7.
Hence, the y-intercept = -7.
Therefore, the y-intercept of two functions A and B are negative.
