Question

CAN SOMONR HELP ME?????? DOES SOMONE KNOW HOW TO DO THIS???????

Answer 1

Answer:

see explanation

Step-by-step explanation:

• Parallel lines have equal slopes

• The slopes of perpendicular lines are the negative reciprocal of each other

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 7x + 2y = 7 into this form

Subtract 7x from both sides

2y = - 7x + 7 ( divide all terms by 2 )

y = - $\frac{7}{2}$ x + $\frac{7}{2}$ ← in slope- intercept form

with slope m = - $\frac{7}{2}$

Thus

slope of perpendicular line = $\frac{2}{7}$

slope of parallel line = - $\frac{7}{2}$
