10. Write the slope-intercept form of the equation of the
Ghella [55]

Answer:

y = -3x + 18

Step-by-step explanation:

The slope intercept form of a line is expressed as y = mx+c

m is the slope

b is the intercept

Get the slope

Given the equation of a line 9x + 3y = 6

Rewrite

3y = -9x + 6

y = -9x/3 + 6/3

y = -3x + 2

Hence the slope of the line is -3

Get the y-intercept

Substitute m = -3 and (5,3) into y  = mx+b

3 = -3(5) + b

3 = -15 + b

3 + 15 = b

18 = b

b = 18

Get the required equation

y = mx+b

y = -3x + 18

This gives the required equation

Given m ll n,<br> find the value of x and y.<br> Can someone answer this today please
Artemon [7]

Answer:

  • x = 15, y = 50

Step-by-step explanation:

m and n are parallel and cut by a transversal

<u>Finding x</u>

  • 8x + 12 + 2x + 18 = 180 (consecutive interior angles sum up to 180°)
  • 10x + 30 = 180
  • 10x = 150
  • x = 15

<u>Finding y</u>

  • 8x + 12 = 3y - 18     (vertical angles are equal)
  • 8(15) + 12 = 3y - 18
  • 132 = 3y - 18
  • 150 = 3y
  • y = 50
