Write an equation in Slope Intercept Form for the following line.
2 answers:
Answer:
The equation in slope intercept form (y = mx + b) is y = 2x - 4
m = the slope
b = the y intercept
The line cross the y-axis at -4 so the y-intercept (b) is -4.
You can use the slope formula since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.
=
= 2
So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

To find the area of a sector of a circle use the next formula:
As the given circle has a outside angle 90º (it is not part of the sector of the circle) subtract the 90º from 360º (total angle of a circle) to find the angle of the sector:
Find the area of the sector with angle 270º:
