A line through (4,-2) with slope -3
1 answer:
Answer: y = -3x + 10
Step-by-step explanation:
Using the formula for finding the equation of line ;
y - = m ( x -
)
= 4
= -2
m = -3
Substituting into the formula , we have
y - (-2) = - 3 ( x - 4 )
y + 2 = -3x + 12
writing the equation of the line in slope - intercept form , this means that we must make y the subject of the formula , that is
y = -3x + 12 - 2
y = -3x + 10

Answer:
52
Step-by-step explanation:
The total shaded are will be the area of big circle - not shaded circle + little shaded circle.
The are of big shaded circle: So, A=
(8^2)= 64
The are of not shaded circle: So, A=
(4^2)= 16
The are of little shaded cirlce: So, A=
(2^2)= 4
64 - 16
+ 4
= 52
