Question

Observe the given graph:

The equation for the graph will be ______

• A. y = 1.1x
• B. 2y = x
• C. y = 0.55x
• D. y = 1.1

Answer 1

The correct option is C y = 0.55x

The points located on the graph are:
(1, 0.55) and (2, 1.1)
You know,
Slope = $\frac{Rise}{Run}=\frac{Changeiny}{Changeinx}$

∴ Slope for the graph will be: $=\frac{1.1-0.55}{2-1}$
$=\frac{0.55}{1}$
or, Slope $\left(m\right)=0.55$

You know, equation of a straight line is $y=mx$

Hence, $y=0.55x$
