This stuff is elementary but for some reason this doesn't make too much sense to me : What's the best way to learn the x and y coordinates and answer the following question. Appreciate your input :
In the xy-coordinate plane, the slope of line l is 3/4. Does line l pass through the point (-2/3, 1/2) ?
(1). Line l passes through the point (4,4)
(2). Line l passes through the point (-4,-2)
Remember y=bx+m .. b is that slope, m is the value of where line intercepts y axys.
1. gives us 4=3/4*4+m
so m =1. now plug -2/3 for x and 1 for m. does it equal to 1/2?. if yes, then the line does pass. suff.
now you can do 2) similar way
