Answer:
[tex]y = -3x + 0.25[/tex]
Step-by-step explanation:
A line has the following slope-intercept equation:
[tex]y = ax + b[/tex]
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 [tex]a = -3[/tex]. So
[tex]y = -3x + b[/tex]
Passes through the point (1.25, -4). Means that when [tex]x = 1.25, y = -4[/tex]
[tex]-4 = -3*1.25 + b[/tex]
[tex]b = -3*1.25 + 4[/tex]
[tex]b = 0.25[/tex]
So
[tex]y = -3x + 0.25[/tex]
