which of the following points are not on the graph on y=-2x+3?
following points ??
the answer choices are (1,1),(-2,3),(-1,5),(2,-1)
so what u can is, put the points in equations.. if it satisfies.. than thats ur answer.. Inside the bracket, they are arranged as (x , y).. start doing for each one..
they dont have a graph! how do u figure it out in ur head
u dont need graph for this.. i will show u an example.. given equation = y=-2x+3 , and consider point (2, -1) So you have x = 2 and y = -1.. substitute in equation.. so -1 = -2 (2) + 3 -1 = -4 + 3 -1 = -1 as LHS = RHS... so this point is on the graph... similarly solve for others and the one in which LHS not equal to RHS is ur answer...
so we figure it out it would be a 1,1 do u think its ritee?
nopes.. it fits in the equation... 1 = -2 (1) + 3 1 = 1 the answer is 2, (-2,3) 3 = -2(-2) + 3 3 = 7.. so it will not fit in the equations and is not on the graph..
can u explaion it step by step on how u got the answer?
whats the equation we have ?? y=-2x+3.. and what is the point we have to check ?? (-2, 3)
now compare this point with, (x, y ) and substitute in equation to solve further..
