Question

Write the equation of the line that is parallel to the line 7 − 4 x = 7 y 7−4x=7y through the point (2,0).

Answer 1

7 - 4x = 7y
1 - 4/7x = y....y = -4/7x + 1...slope here is -4/7. 
A parallel line will have the same slope

y = mx + b
slope(m) = -4/7
(2,0)...x = 2 and y = 0
now sub and find b, the y int
0 = -4/7(2) + b
0 = -8/7 + b
8/7 = b

so ur parallel equation is : y = -4/7x + 8/7 <=
