Question

Are the lines 7x – 4y = 3 and x – 4y = 3 parallel, perpendicular, or neither?

Answer 1

neither

Answer 2

parallel lines have the same slope. Perpendicular lines have slopes with the following relation:
\[m _{1}m _{2}=-1\]Put the equations in slope-intercept form and to check.

Answer 3

ohhh

Answer 4

\[y=\frac{7}{4}x-\frac{3}{4}\]and\[y=\frac{1}{4}x-\frac{3}{4}\]The slopes we need to check are 7/4 and 1/4. Since they dont fit either criteria, they are neither parallel nor perpendicular.

Answer 5

thanks

Answer 6

Which is an equation in slope-intercept form of the line that contains the points S(7, –9) and T(8, –7)?
