Through: (2, -1) parallel to y=-2/5x+3

Step-by-step explanation:

The formula for a line in slope-intercept form is y=mx+b.

Two parallel lines have the same slope.  Therefore, m should be the same for both equations.

As of now, we know that the equation must be .  We must find the b value -- in order to find it, we will use the point given.  We are told that the line must pass through the point (2,-1), where y=-1 when x = 2.  Plug in those values into the equation and solve for b.

Therefore, the final equation is

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
