Jus plot the points in then draw a line through them.
I will attach a graph example of it
The slope is the rate of change
You can find it in two ways
1: visually, draw a triangle and count from vertically to horizontally
2: slope formula - I will show it this way
(Y2-y1)/(x2-x1)
Given points (3,12), (4,16)
(16-12)/(4-3) = 4/1 = 4
The slope is 4
The slope represents the $ per hour. In this case, the wage is $4 per hour.
4/3
1.3 repeating
1 1/3
These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
Angle ∠ A = α = 44.049° = 44°2'55″ = 0.769 rad
Angle ∠ B = β = 52.617° = 52°37' = 0.918 rad
Angle ∠ C = γ = 83.335° = 83°20'4″ = 1.454 rad
Number b will the right answer
