Which choice is the equation of a line that passes through point (7, 3) and is parallel to the line represented by this equation?y=2/7x-3
A. 7x + 3y = 2
B. y=2/7x+1
C. y=-7/2x-3
D. 2x + 7y = 1
**Weegy:**
A. 7x + 3y = 2 **User:** Which choice could be the equation of a line perpendicular to the line represented by this equation?
y = 5
A. y = 4x- 9
B. y=-1/5x
C. y = 5x
D. x = 5
**Weegy:** y = 5
This is an equation of a horizontal line that crosses the y-axis at (0, 5)
A perpendicular line would be a vertical line, whose equation looks like x = #, D is the only one that fits the case **User:** Which choice is the equation of a line that has a y-intercept of –3 and is perpendicular to the line represented by this equation?
y=2/3x+1 A.
B. y = 3x- 3
C. y=-3/2x-3
D. y=3/2x+3
