Plz help. Write the slope intercept form of the equation.

y = - 1.5x - 5 or y = - 3/2x - 5

Step-by-step explanation:

Step 1:

y = mx + b           Slope Intercept Form

Step 2:

1 = - 3/2 ( - 4 ) + b          Equation

Step 3:

1 = 6 + b         Multiply

Step 4:

b = - 5         Subtract 6 on both sides

y = - 1.5x - 5

Hope This Helps :)

paper clips = $1.85

index cards = $3.95

Step-by-step explanation:

Mark

12 paper clips = x

10 index cards = y

$61.70 total

Janice

15 paper clips = x

7 index cards = y

$55.40 total

12x + 10y = 61.70

15x + 7y   = 55.40

*** you want to cancel out one of the letters

(12x + 10y = 61.70) * -7

(15x + 7y   = 55.40) * 10

-84x -70y = -431.9

150x + 70y = 554.0

150x + 70y = 554.0

-84x -70y = -431.9

66x + 0 = 122.1

66x = 122.1

x = 122.1 ÷ 66

x = 1.85

plug it back in

15(1.85) + 7y   = 55.40

27.75 + 7y   = 55.40

7y   = 55.40 - 27.75

7y = 27.65

y = 27.65 ÷ 7

y = 3.95
