Question

2
1 point
The point, (-3, 7), is on the line y = -3x+7.
True
O False

Answer 1

Explanation:

• in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
• If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
• Now let us plug in the value of x=-3
• 
  `y = - 3( - 3) + 7 \\ y = - 9 + 7 \\ y = - 2`
• now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
• therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.
