Answer:
m = 4/3
Step-by-step explanation:
To find the slope of a line use the formula, where "m" means slope:

*You don't need to show this part on paper*
Choose which point you want to be point 1 and point 2. Remember the points are written (x, y).
Point 1: (-2, 1) x₁ = -2 y₁ = 1
Point 2: (4, 9) x₂ = 4 y₂ = 9
Substitute the coordinates into the formula:
*Show this part on paper*

Simplify
Reduce by dividing by 2
Slope
The slope of the line is 4/3
Answer:
The answer is option 1.
Step-by-step explanation:
Firstly, you have to elaborate the expression :


Next you have to take out the common factors and factorize it :



An angle formed by a chord and a tangent line is half the measure of the intercepted arc.
The intercepted arc is ADB, which is given as 162 degrees.
Angle EAB = 1/2 of 162
The answer is 81 degrees.
