Question

write a slope - intercept equation for a line with the given characteristics.
m = - 8.1, y - intercept (left(0,\frac{2}{5}
ight))
the slope - intercept equation for a line with the given characteristics is (square).

Explanation:

Step1: Recall slope-intercept form

The slope-intercept equation of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept value.

Step2: Substitute given values

Substitute $m = -8.1$ and $b = \frac{2}{5}$ into the formula:
$y = -8.1x + \frac{2}{5}$
(Note: $\frac{2}{5}$ can also be written as $0.4$, so the equation can also be written as $y = -8.1x + 0.4$)

Answer:

$y = -8.1x + \frac{2}{5}$ (or $y = -8.1x + 0.4$)
