Question

Find the slope and y-intercept of each linear equation 30 points

Answer 1

Explanation:

The slope-intercept form:

• y = mx + b, where m- slope, b- y-intercept

Given lines:

1)

• y = - 2x + 7
• m = - 2, b = 7

2)

• y = 6x + 11
• m = 6, b = 11

3)

• y = -2.5x + 3.2
• m = - 2.5, b = 3.2

4)

• y = 1/4x - 2/7
• m = 1/4, b = - 2/7
