Answer 2

Answer:

$y = -3x + 0.25$

Step-by-step explanation:

A line has the following slope-intercept equation:

$y = ax + b$

In which a is the slope.

Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).

Slope of -3 means that $a = -3$. So

$y = -3x + b$

Passes through the point (1.25, -4). Means that when $x = 1.25, y = -4$

$-4 = -3*1.25 + b$

$b = -3*1.25 + 4$

$b = 0.25$

So

$y = -3x + 0.25$
