Answer:
the cercomference is 220
Step-by-step explanation:
X y
2 7
0 3
I figured out how to do it.
2-0=2
7-3=4
4/2=2 therefore the gradient is 2.
Now we need the y intercept which is already given (the y intercept is when x=0) when x equals 0 x=3 so the equation of the line is:
y=2x+3
Hope this helps :)

Answer:
y-30 = 3(x-1)
Step-by-step explanation:
Point-slope form of an equation is
y-y1 = m(x-x1) where (x1,y1 ) is a point and m is the slope
We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes. The rate increased 3 minutes each day so m = 3
y-30 = 3(x-1)
