Slope intercept form is y = ax + b, where a is equal to the slope value, and b is equal to the y-intercept.

You have both the slope and y-intercept, which means that all you need to do is plug in the numbers to the equation in order to get your answer!

Let's plug in -7 for a, which gives you y = -7x + b.

Next, we'll plug in the y-intercept, which gives you y = -7x + 9.

Hope this helps!! :)

A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72.
Elena-2011 [213]

We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.

36.72/x = 85/100

Solve  for x.

x=36.72/0.85

x=43.2

So, the bill was $43.20 before applying the voucher discount of 15% off.

Pls help I don't understand !! !!
NemiM [27]
100cm is equivalent to 1m so 500cm is equivalent to 5m. What you need to do is divide 500cm (5metres) by 25cm (one quarter of a metre). So the number sentence using 'division' should look like 500cm divided by 25cm which equals 20. Don't forget to use proper symbols for division though. Let me know if this helps:)
