Write the equation of a line that passes through the given point and is parallel to the given line.
monitta

Answer:

  1. y=2x+5
  2. y= 1/3x -4

Step-by-step explanation:

1.

(1,-3)=(x_1,y_1)\\\\y =2x+2\\\\m = 2

Substitute values into point-slope form

y-y_1=m(x-x_1)\\\\y -3 =2(x-(-1))\\\\y-3=2(x+1)\\\\y-3=2x+2\\\\y=2x+2+3\\\\y=2x+5

2.

(18,2) =(x_1,y_1)\\\\3y-x=-12

Arrange equation in slope-intercept form (y=mx+b)and derive slope

3y =x-12\\\\\frac{3y}{3} =\frac{1x}{3} -\frac{12}{3} \\\\y = \frac{1}{3} x -4\\\\m = \frac{1}{3}

Substitute values into point-slope form

y-y_1=m(x-x_1)\\\\\\y-2=\frac{1}{3} (x-18)\\\\y-2=\frac{1}{3} x -6\\\\y=\frac{1}{3} x -6+2\\\\y=\frac{1}{3} x -4

STEP BY STEP, LONG DIVISION
8_murik_8 [283]

Answer:

.53

Step-by-step explanation:

divide 8 by 15 and you get 0.53 explanation As a decimal 8/15 is 0.533 (3 repeating) or about 0.53. To convert 8/15 into a decimal value we simply divide 8 by 15. Since 15 cannot be divided into 8 we add a decimal and a zero then divide 15 into 8, giving us 5 with 5 remaining. Adding another zero allows us to divide 15 into 50 3-times with 5 remaining.
