Answer:

a = \frac{9}{2}

Step-by-step explanation:

To find the value of a, find the Slope of both the equations.

For lines to be perpendicular to each other    m_{1}m_{2}  = - 1

For line 1:

2x + 3y − 6 = 0 represent the line in y=mx +c form

3y = -2x + 6

y = \frac{-2}{3} x + \frac{6}{3}

y = \frac{-2}{3} x + 2

m_{1} = \frac{-2}{3}

For line 2:

ax - 3y = 5

ax = 5 + 3y

ax - 5 = 3y

y = \frac{ax}{3} - \frac{5}{3}

m_{2} = \frac{a}{3}

Apply the condition of perpendicularity:

\frac{-2}{3} * \frac{a}{3} = - 1

\frac{2a}{9} = 1

a = \frac{9}{2}

Answer:

{x}^{2}  + 2x + 1 = 17 \\  {x}^{2}  + 2x - 16 = 0 \\ x =  \frac{ - b± \sqrt{ {b}^{2}  - 4ac} }{2a}  \\ x =  \frac{ - 2± \sqrt{68} }{2}  \\ x =  \frac{ - 2±2 \sqrt{17} }{2 }  \\ x =  - 1± \sqrt{17}

Abigail and Spencer calculate the slope of the line between the points (3,-1) and (5,4) in different ways. Abigail calculates th
telo118 [61]

Answer:

Spencer and Abigail are correct

Lauren is incorrect

Step-by-step explanation:

Spencer and Abigail are correct

Slope = change in y ÷ change in x

Or  m=\dfrac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1) = (3, -1)

Let (x_2,y_2) = (5, 4)

\implies m=\dfrac{4-(-1)}{5-3}=\dfrac52

This is Spencer's method

Let (x_1,y_1) = (5, 4)

Let (x_2,y_2) = (3, -1)

\implies m=\dfrac{-1-4}{3-5}=\dfrac52

This is Abigail's method

It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.

Lauren's calculation is wrong as she calculated her slope as:

m=\dfrac{y_2-y_1}{x_1-x_2}

where it should have been m=\dfrac{y_2-y_1}{x_2-x_1}
