Question 903074: A line has the x-intercept 12 and y-intercept 7.
The slope of the line is m = ?

An equation for the line is?

--------------------------------------------------------------------------------

A line L has the equation 30x + 2y = 10.
Find an equation for the line that passes through the point (-17, -11) and is parallel to L.

The slope of the line through (-17, -11) perpendicular to L is
m = ?

please explain how these are solved. Thank you

X intercept is (12,0).
Y intercept is (0,7).

Then using the slope intercept form,

.
.
Parallel means it has the same form but a difference right hand side.

Use the point to solve for .

.
.
.
Perpendicular lines have slopes that are negative reciprocals.

The slope of the first line is
