Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.
a.
x – y = 6
b.
2x – y = 6
c.
2x – y = 1
d.
2x – y = –1

Y = 2x - 1the slope here is 2. A parallel line will have the same slope.

y = mx + b
slope(m) = 2
(4,2)x = 4 and y = 2
now we sub and find b, the y int
2 = 2(4) + b
2 = 8 + b
2 - 8 = b
-6 = b

ur equation is : y = 2x - 6but we need it in standard form...
y = 2x - 6
-2x + y = -6 ...multiply by -1
2x - y = 6 <===

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
