Question

Write a slope-intercept form equation to represent Caleb's savings situation, where he starts with $60 and puts $10 extra each week.

a) y = 10x + 60
b) y = 60x + 10
c) y = 10x - 60
d) y = 60x - 10

Answer 1

The correct slope-intercept form equation to represent Caleb's savings, where he starts with $60 and puts away an additional $10 each week, is a) y = 10x + 60.

Step-by-step explanation:

To represent Caleb's savings situation, we can use the slope-intercept form of the equation, which is y = mx + b, where m is the slope and b is the y-intercept. The slope (m) represents the rate of change, in this case, the amount Caleb saves each week, which is $10. The y-intercept (b) represents the starting amount, which is $60 in Caleb's case. This means when x (the number of weeks) is 0, Caleb has $60. Therefore, the correct equation to represent Caleb's savings situation in slope-intercept form is a) y = 10x + 60.
