Question

aa.7 write a linear equation from a graph whm
write the equation of this line in slope - intercept form.
write your answer using integers, proper fractions, and improper fractions in simplest form.

Explanation:

Step1: Identify two points

Points $(-1, 4)$ and $(1, -4)$ are on the line.

Step2: Calculate slope $m$

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 - 4}{1 - (-1)} = \frac{-8}{2} = -4$

Step3: Find y-intercept $b$

Line passes through $(0,0)$, so $b = 0$.

Step4: Write equation

$y = mx + b = -4x + 0 = -4x$

Answer:

$y = -4x$
