<span>scott's method is linear because the number of minutes increased by an equal number every week. Because he increased each week by 5 minutes while Harry increased by a different amount of time each week</span>
Answer:
2.7, or 2

Step-by-step explanation:
Step-by-step explanation:
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
so, in our case, the slope is 2, the y-intercept is -3.
the y-intercept gives you the first point : (0, -3)
using the slope of 2 we know that for every unit x increases, y increases by 2.
so, you can pick a next point e.g. x = 2, which makes y = -3 + 2×2 = -3 + 4 = 1
that gives us (2, 1)
mark both points on the chart and then draw a straight line through both points.
Area = base (height) 1/2
so you plug your numbers into the equation and solve
42 = 6(x) 1/2
42 = 3(x)
divide each side by 3
14 = x
Proof:
3 consecutive integers are x, x+1 , x+2.
Add these values.
x+x+1+x+2
3x+3
3×(x+1)
3(x+1) is the multiple of 3 for any integer value of x.
