How do you find out if a like is parallel, perpendicular, or coincidental when theres 2 equations
finlep [7]

The slope intercept form of the equation of a line is given as:

y = mx + c

where m = the slope of the line

c = the y - intercept of the line

1) Two line are parallel if they have the same slope

That is:

\begin{gathered} \text{If the equation for line 1 is: y = m}_1x+c_1 \\ \text{If the equation for line 2 is:  y = m}_2x+c_2 \\ \text{Then, line 1 is parallel to line 2 if m}_1=m_2 \end{gathered}

2) Two equations are perpendicular if the slope of one is the negative inverse of the other.

\text{That is : m}_1=\text{ }\frac{-1}{m_2}

3) Two equations are coincidental if they have the same slope and the same y intercept

\begin{gathered} \text{That is: m}_1=m_2_{} \\ \text{and c}_1=c_2 \end{gathered}

<em>If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).</em>


<em>If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).</em>

Hi please i need the complete step-by-step solution for number 5. thank you​
Nataliya [291]

Answer:

8

Step-by-step explanation:

( 12 + 3m ) / 2 = 18

12 + 3m = 18 x 2

12 + 3m = 36

3m = 36 - 12

3m = 24

m = 24 / 3

m = 8
