Given:

Equation of a line is

[tex]3x-4y=8[/tex]

To find:

The equation of line in slope intercept form that is parallel to line a and goes through point (24, 6).

Solution:

If a linear equation is [tex]ax+by+c=0[/tex], then

[tex]Slope=-\dfrac{a}{b}[/tex]

In the equation [tex]3x-4y=8[/tex], a=3 and b=-4, thus the slope of the line is

[tex]Slope=-\dfrac{3}{-4}[/tex]

[tex]Slope=\dfrac{3}{4}[/tex]

We know that, slope of two parallel lines are same. So, slope of parallel line is

[tex]m=\dfrac{3}{4}[/tex]

The parallel line passes through (24, 6) and have slope [tex]m=\dfrac{3}{4}[/tex], so the equation of line is

[tex]y-6=\dfrac{3}{4}(x-24)[/tex]

[tex]y-6=\dfrac{3}{4}(x)-\dfrac{3}{4}(24)[/tex]

[tex]y-6=\dfrac{3}{4}(x)-18[/tex]

Add 6 on both sides.

[tex]y=\dfrac{3}{4}(x)-18+6[/tex]

[tex]y=\dfrac{3}{4}(x)-12[/tex]

Therefore, the equation of parallel line in slope intercept form is [tex]y=\dfrac{3}{4}(x)-12[/tex].
