Question

The equation for line g can be written as y =10/9 x −6 . Line h, which is parallel to line g, includes the point (4, 5) .What is the equation of line h ?

Answer 1

To be parallel, the line has to have the same slope as the other. In this case, this slope is 10/9.

We can write this equation in slope-intercept form:

y = 10/9x + b

Now, let's input our coordinate point and solve for b.

5 = 10/9(4) + b
Multiply everything out.
5 = 40/9 + b
Subtract 40/9 from both sides.
5/9 = b

The equation of line h is:

y = 10/9x + 5/9
