If a line has the equation of y = 2x - 3, is (4,3) a point on this line?

OpenStudy (anonymous):

Plug 4 in for x in that equation. Is the result 3?

OpenStudy (ghazi):

just substitute 4 at X and 3 at Y if both the sides are equal then condition is satisfied and hence point lies on the line

OpenStudy (ghazi):

if not then point doesn't lie on the line
