Question

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 lines into this form

10x + 6y = 8 ( subtract 10x from both sides )

6y = - 10x + 8 ( divide all terms by 6 )

y = - $\frac{5}{3}$ x + $\frac{4}{3}$ ← line 1

with slope m = - $\frac{5}{3}$

y = $\frac{3}{5}$ x - 7 ← line 2

with slope m = $\frac{3}{5}$

3y = 5x + 2 ( divide all terms by 3 )

y = $\frac{5}{3}$ x + $\frac{2}{3}$ ← line 3

with slope m = $\frac{5}{3}$

Thus

Lines 1 and 2 are perpendicular

Lines 1 and 3 are neither

Lines 2 and 3 are neither
