This equation is written in point-slope form.
In this equation we have the point (2, 12) and the slope of 4.
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Use the point (2, 12) to solve.
12 = 4(2) + b
12 = 8 + b
12 - 8 = 8 + b - 8
4 = b (y-intercept)
Hope This Helped! Good Luck!
To find x, replace y as 0 and solve. To find y, replace x with 0 and solve.
Answer:
Must save 8 weeks or more to purchase the bike.
Step-by-step explanation:15*w >= 120 where W is the number of weeks.
w >= 120/15 = 8
