Yes, he is correct because both the lines have same slope.
The two equations are:
Two lines are parallel only if their slopes are equal.
So, let us write each equation in slope-intercept form , where, is the slope of the line.
Equation 1 is:
So, the slope of line 1 is
Now, equation 2 is:
Therefore, slope of line 2 is,
Therefore, both the lines are parallel to each other.
A and D are parallel.
Refer to the slope-intercept equation (y = mx + b).
M = the slope
If the slopes are equal, then the lines are parallel.
The slope for line A is 2, and so is the slope for line D.
Line A and line D are parallel.
Lines with the same slope are parallel. 2x-5 and 2x+5 have the same slope
parallel lines because the slopes of the lines are the same
the lines are parallel
You haven't attached any equations so I can't solve this however:
Parallel lines when plotted always have the same gradient.
The general form of line is y = mx + c where "m" is the gradient.
So parallel lines will have "m" to be the same value.
Examples are: y = 6x + 4 and y = 6x - 99
: y = -4x + 2 and y = -4x + 5
1) is right
