Question

Identify the correct equation for the given line.

• A. $y=0.6x-3$
• B. $y=0.6x+3$
• C. $y=-0.6x-3$
• D. $y=-0.6x+3$

Answer 1

The correct option is A $y=0.6x-3$


From the graph, we can observe,
y-intercept value = (-3, 0)
$\Rightarrow b=-3$

We know,
$\text{Slope (m)}=\frac{\text{Rise}}{\text{Run}}$

Putting values, we get,
$\text{Slope (m)}=\frac{1.2}{2}$
$=\frac{12}{20}$
$=0.6$

We know, equation of a straight line in the point-slope form is,
$y=mx+b$

Putting the values, we get,
The equation of the line is $y=0.6x-3$.
