Answer:
y=3x+2
Step-by-step explanation:
y=mx+b. The m would equal 3 because it goes up 3 and over 1. The b would equal 2 because that is the y-intercept.
a) Slope = 1 hour / 3 kilogram = 20 minutes per kilogram.
b) 20 minutes x 4 kilograms = 1 hour and 20 minutes total
Answer:
2x - 5y = -13
Step-by-step explanation:
The equation of a straight line can be written as
(y - y1) = m(x - x1), where the coordinates are (x1,y1) and gradient is m.
Hence by applying this formula, we get:
y - 1 = 2/5 (x + 4)
5y - 5 = 2(x + 4) (Multiply both sides by 5)
5y - 5 = 2x + 8 (Expand the Right Hand Side)
5y - 2x = 13 (Bring the variables to one side)
2x - 5y = -13 (Multiply both sides by -1)
Hence Answer is <u>2x - 5y = -13</u>

Answer:
45°
Step-by-step explanation:
The base angles in any isosceles triangle are congruent.
? = 45°
__
The acute angles in any right triangle are complementary.
? = 90° -45° = 45°
__
However you decide to think about it, you get ? = 45°.
