Parallel to y=2x-9, passing through (1,-5)
To find the equation of the required line under the given conditions
(i) point-slope form: the slope of the line with equation y=mx+c is m. Now use the fact that two lines are parallel if and only if they have the same slope. So the required line has slope 2. Use the additional information that this passes through (1,-5) to determine the equation in the required form.
(2) slope-intercept form: This is the equatio...
