b=a-(a*.2)
You asked:
Investigate the equation: \(b = a - a \cdot .2\).
MathBot Answer:
The graph of \(b = a - a \cdot .2\) is a line.
The a-intercept is \(0\).
The b-intercept is \(0\).
The slope of the line is \(\frac{4}{5}\).
The slope-intercept form of the line is \(b = \frac{4 a}{5} + 0\).
The line in standard form is \( - 4 a + 5 b + 0 = 0 \)
