Answer 1

Answer:

C) $y=-\frac{1}{5}x$

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b

where m is the slope of the line, b is the y intercept (value of x when y is 0) and y, x are variables.

The equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)$

From the graph, the line passes through (0, 0) and (10, -2), hence the equation of the line is:

$y-0=\frac{-2-0}{10-0}(x-0)\\\\y=-\frac{1}{5}x$
