Question

1. Identify the RATE OF CHANGE and INITIAL VALUE from

Answer 1

Here, Rate of change means Slope and initial value means y-intercept. The equations given above are written in slope-intercept intercept form i.e.

$\bf \: y = mx + b$

Where,

• m is slope
• b is the y-intercept

$\tt \: y = 3x + 6$

• Rate of change = 3
• Initial value = 6

$\tt \: y = - 7x + 5$

• Rate of change = -7
• Initial value = 5

$\tt \: y = 9x + 4$

• Rate of change = 9
• Initial value = 4
