Slope-intercept form can be written as
y = mx + b
From the question above, we should move x to another side (right side), so the left side only contains of y-variable
-3x + 2y = 12
2y = 12 + 3x
To make slope-intercept form, only y is on the left side. We should move the coefficient 2 to the right side.
2y = 12 + 3x
2y = 3x + 12
y = (3x + 12)/2
Simplify the equation
y = (3x + 12)/2
y = (3/2)x + 12/2
y = (3/2)x + 6
This is the final answer ⇒ y = (3/2)x + 6
We are given points (30,4) , (60,8) and (90,12)
To calculate the rate per minute at which the air freshener dispenses sprays,
we can use two points to find slope.
The formula for slope is given by :
let us use two points (60,8) and (90,12) to find the slope,
Slope = 4/30
So the rate per minute at which the air freshener dispenses sprays is 4/30.
So first option is correct answer .
Assume if it is cloudy, then you are outside.
