The slope-intercept form of a line is:
y = mx + b
Where m is the slope and b is the y-intercept.
Two lines having slopes <em>m1</em> and <em>m2</em> are perpendicular if
m1 * m2 = -1
We are given the equation of one line:
It's required to find the equation of another line that is perpendicular to it. We have m1 = 1/3, let's find the other slope:
The slope of the required line is -3. Now we use the point through which the line passes (-2, 2).
We use the point-slope form of the line:
y - k = m( x - h)
Where (h,k) = (-2, 2) is the point. Substituting:

Answer:
Graham gets 3/4 of the money, or £22.50 and Ahir gets 1/4 of it: £7.5.
Step-by-step explanation:
Add 3 and 1: 3 + 1 = 4.
Then Graham gets 3/4 of the money, or £22.50 and Ahir gets 1/4 of it: £7.5.
Check: is the ratio
£22.5
---------- equal to 3:1? YES
£7.5
Do £7.5 and £22.5 sum up to £30? YYES
---------- =

Your 4th option would be ur correct one
Step-by-step explanation:
= 4,830 - 3,57 × 10³
= 4,83 - 3,57 × 1.000
= 4,83 - 3.570
= -3.565,17
= -3,56517 × 10³
≈ -3,57 × 10³
