Which lines are parellele
natali 33 [55]

Line 1 and Line 4 are parallel lines

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept of the line.

<u>To find the slope of each line:</u>

Line 1: y=-\frac{3}{4} x-6

Slope (m_1)=-\frac{3}{4}

Line 2: y-7=-4(x+9)

y-7=-4x-36

Add 7 on both sides, we get

y=-4x-29

Slope (m_2)=-4

Line 3: y=-2 x+6

Slope (m_3)=-2

Line 4: x+\frac{4}{3} y=-5

Subtract x from both sides, we get

\frac{4}{3} y=-x-5

Multiply  by \frac{3}{4} on both sides, we get

y=-\frac{3}{4}x-\frac{15}{4}

Slope (m_4)=-\frac{3}{4}

<em>Two lines are parallel, if their slopes are equal.</em>

From the above slopes,

m_1=m_4

Therefore Line 1 and Line 4 are parallel lines.
