What is the equation of the line that passes through the point (-1,7) and is parallel to the line y= -2x-1

if we look at the equation y = -2x - 1, is already in slope-intercept form, therefore, has a slope of -2.

now, parallel lines have exactly equal slopes, therefore a parallel to that one above, will have also a slope of -2, so we're really looking for a line whose slope is -2 and runs through -1, 7.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
