The slope/rate of change for the interval of f(0) to f(4) is 2
The slope of change for the interval of f(4) to f(8) is 1/4
function B has larger slope
function A has larger y intercept
How to find the slope
The slope is represented as m, The slope by definition is the ratio change of the output values to the input values
the slope, m calculating using the points on the graph (4, -1) and (8, 0)
m = (y₀ - y₁) / (x₀ - x₁)
m = (-1 - 0) / (4 - 8)
m = (-1) / (-4)
m = 1/4
The straight for linear equation is constant
The y intercept for the graph is -2 from (0, -2)
the slope, m calculating using the points on the graph (0, 1) and (4, 9)
m = (y₀ - y₁) / (x₀ - x₁)
m = (1 - 9) / (0 - 4)
m = (-8) / (-4)
m = 2
The straight for linear equation is constant
The y intercept for the graph is 1 from (0, 1)
