Answer:

x=1

Step-by-step explanation:

Step 1- Distribute -5 into (1+5x), which gives you the equation

             -31-4x=-5-5-25x

Step 2- -31-4x=-10-25x

                 +4x      +4x

Step 3- -31=-10-21x

            +10 +10

Step 4- -21/-21=-21x

Conclusion- x=1

Answer:

x=1

Step-by-step explanation:

-31 - 4x= -5 - 5 (1+5x)

-31-4x=-5-5-25x

Separate the different variables and solve.

-31+5+5=4x-25x

-31+10=-21x

-21=-21x

x=1

Find the equation of the line that contains the given point and the given slope. Write the equation in slope-intercept form.
stealth61 [152]

The slope-point form of a line:

y-y_0=m(x-x_0)

The slope-intercept form of a line:

y=mx+b

1.

m=6,\ (4,\ 1)\to x_0=4,\ y_0=1

Substitute

y-1=6(x-4)\qquad|\text{use distributive property}\\\\y-1=6x-24\qquad|\text{add 1 to both sides}\\\\\boxed{y=6x-23}

2.

m=-5,\ (6,\ -3)

Substitute

y-(-3)=-5(x-6)\qquad|\text{use distributive property}\\\\y+3=-5x+30\qquad|\text{subtract 5 from both sides}\\\\\boxed{y=-5x+24}

3.

m=-\dfrac{1}{2},\ (-8,\ 2)\\\\y-2=-\dfrac{1}{2}(x-(-8))\\\\y-2=-\dfrac{1}{2}(x+8)\\\\y-2=-\dfrac{1}{2}x-4\qquad|\text{add 2 to both sides}\\\\\boxed{y=-\dfrac{1}{2}x-2}

4.

m=0,\ (-7,\ -1)\\\\y-(-1)=0(x-(-7))\\\\y+1=0\qquad|\text{subtract 1 from both sides}\\\\\boxed{y=-1}
