Question

1. In the linear equation y = 3x + 2, what is the slope? ALSO, if y equals 14 what is x equal to

Answer 1

Explanation:

Linear equation: y =mx + b

Therefore,

y = 3x+ 2

Slope (m) = 3

When y =14,

14 = 3x + 2 {Subtract 2 form both sides}

14- 2 = 3x + 2 -2

12 = 3x {Divide both sides by 3}

12/3 = 3x/3

4 = x

x = 4

Answer 2

slope = 3

(4,14)

Explanation:

y = 3x + 2

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

m = 3

Let y = 14

14 = 3x+2

Subtract 2 from each side

14-2 = 3x+2-2

12 = 3x

Divide by 3

12/3 = 3x/3

4 =x
