Step 1: simplify

[3.4 ( 6 x + 2 ) +3] + 4 p -3 x 

Pemdas!

 6x+2=8x

3.4+3=6.4

6.4+8x=14.4

14.4x+4p=18.4xp+3= 21.4xpx 

x=8

p=18.4

Other x = 21.4

Match each equation to its equivalent equation in slope-intercept form.
Bumek [7]
1.) y+6=3(x+2)    C
     y+6=3x+6
     y=3x+6-6
     y=3x+6
2.) y=1/2(x+8)-2    B
     y=1/2x+4-2
     y=1/2x+2
3.) y+1=1(x-3)    E
     y+1=x-3
     y=x-3-1
     y=x-4
4.) -4x+y=-2    A
     y=-4x-2
5.) 2x-4y=-4     F
     -4y=-2x-4
     y=-2/-4x-4/-4
     y=2/4x+4/4
     y=1/2x+1
6.) 2x+4y=8     D
     4y=-2x+8
     y=-2/4x+8/4
     y=-1/2x+4/2
     y=-1/2x+2

Equation for ( 6, 13) ( 7900, 5 )
tia_tia [17]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y=mx+b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

(x_ {1}, y_ {1}) :( 6,13)\\(x_ {2}, y_ {2}): (7900,5)

We find the slope of the line:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5-13} {7900-6} = \frac {-8} {7894} = - \frac {4} {3947}

Thus, the equation of the line is of the form:

y = - \frac {4} {3947} x + b

We substitute one of the points and find b:

13 = - \frac {4} {3947} (6) + b\\13 = - \frac {24} {3947} + b\\13+ \frac {24} {3947} = b\\b = \frac {51335} {3947}

Finally, the equation is:

y = - \frac {4} {3947} x + \frac {51335} {3947}

Answer:

y = - \frac {4} {3947} x + \frac {51335} {3947}
