How do you find the slope of the line with the given information A) #2x+y=7# B) the line is perpendicular to #y=10x + 7#?
We first rewrite the first equation in slope-intercept form.
(A) This is quite easy: subtract
(B) If two lines are perpendicular, multiplying their slopes will allways give a result of
The equation is allready in slope-intercept form with a slope of
