At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 from this account for her contact lenses. After 3 months she has $255 left in her account. Write an equation in slope-intercept form to represent the relationship between the time that has passed and the amount of money left in Monica's account. Let x represent the time in months and y represent the amount of money remaining in the account.

An equation in the slope-intercept form is:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  m is the rate of change or slope and b is the y-intercept

Given

Given that every month Monica withdraws $15 from this account for her contact lenses

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting , and in the slope-intercept form to determine the y-intercept

switch sides

Thus, the y-intercept b = 210

Now, substituting and in the slope-intercept form of the line equation

Hence, an equation in the slope-intercept form is:

43

step-by-step explanation:

the first one, all those points on the line just make a strait line.
