Answer:

The values of a and b are 6 and 4, respectively.

Step-by-step explanation:

Geometrically speaking, any line is represented by equation of the form:

y = m\cdot x + b (1)

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

m - Slope, dimensionless.

b - y-Intercept, dimensionless.

In addition, the slope is defined in terms of distinct known points. That is:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} (2)

If we know that (x_{1},y_{1})=(4,b), (x_{2}, y_{2}) = (a, 8) and m = 2, then the slope is:

\frac{8-b}{a-4} = 2

8-b = 2\cdot (a-4)

8-b = 2\cdot a -8

b = 16-2\cdot a

There is more than one option. If we assume that a = 6, then b is:

b = 16-2\cdot (6)

b = 4

The values of a and b are 6 and 4, respectively.
