Question

Find the slope for each equation

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

2. 3x - y = 5
2x + y = -3

3. y = x + 4
y = x + 4

Answer 1

Explanation:

y = mx + b where m = slope

1.

y = 2x + 3 ; slope = 2

2x - y = 5 ;

y = 2x - 5 so slope = 2

2.

3x - y = 5 ;

y = 3x - 5 so slope = 3

2x + y = -3

y = -2x - 3; so slope = -2

3.

y = x + 4 ; slope = 1

y = x + 4; slope = 1
