Step-by-step explanation:
Question 8
Let the equation of a line passing through two points and
is given by,
y = mx + b
Here, m = slope and y-intercept = b
Since, m =
For two points (1, 4) and (5, 8),
m =
m = 1
Equation will be,
y = (1)x + b
y = x + b
Since, this line passes through (1, 4),
4 = 1 + b
b = 3
Therefore, equation of the line will be,
y = x + 3
Question 9
Let the equation is y = mx + b
m =
For two points (2, 10) and (6, 4)
m =
m =
By substituting the value of 'm' in the equation,
y =
Since, this line passes through (2, 10)
10 =
b = 10 + 2
b = 12
Therefore, equation of the line will be,
We have been given a diagram. We are asked find the measure of arc EAB.
First of all, we will find the measure of arcs ED and CB using our given information.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.
Similarly, we will find the measure of arc DCB.
Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
