Step-by-step explanation:
From Analytical Geometry we get that linear functions can be found after knowing a point and its slope. The standard form of a linear function is represented by the following formula:
(Eq. 1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
At first we need to calculate the y-Intercept, which is cleared within (Eq. 1):
If we know that ,
and
, then the y-Intercept of the linear function is:
Line with a slope of that goes through the point (2, 1) is represented by
.
Lastly, we graph the line by using a plotting software (i.e. Desmos), whose result is included below as attachment.
