00:00 Choose the correct answer
00:03 Let's check all points according to X and Y axis coordinates
00:06 On the left is the X-axis, and on the right is the Y-axis
00:10 This point is not on the line
00:15 We'll use this method for all points, and check which ones are on the line
00:46 Only this point is on the line

Step-by-step solution

If we plot all the points, we'll notice that point (3,5) (3,5) is the correct one, because:

x=3,y=5 x=3,y=5

And they intersect exactly on the line where the graph passes.

3

Final Answer

The graph passes through (3,5) (3,5) .

Key Points to Remember

Essential concepts to master this topic
  • Graph Reading: Identify the exact x and y coordinates where the line passes
  • Technique: Check if point (3,5) lies on the line by locating x=3, y=5
  • Verification: Trace vertical line from x=3 to meet horizontal line from y=5 āœ“

Common Mistakes

Avoid these frequent errors
  • Confusing x and y coordinates
    Don't read (3,5) as x=5, y=3 or mix up the order! This flips the coordinates and makes you check the wrong point. Always remember the first number is x (horizontal) and second is y (vertical).

FAQ

Everything you need to know about this question

How do I read coordinates from a graph accurately?

+

Start at the origin (0,0). Move right for positive x-values, then up for positive y-values. Remember: x comes first in (x,y), so go right first, then up!

What if the line seems to pass close to a point but not exactly through it?

+

In math, close doesn't count! The line must pass exactly through the point. If it's even slightly off, that point is not on the line.

How can I tell if (3,5) or (5,3) is correct without guessing?

+

Look at the graph systematically! Find x=3 on the horizontal axis, trace up to the line, then check what y-value you hit. Do the same for x=5. Only one will match exactly.

Why do some answer choices mention intercepts?

+

Intercepts are special points where the line crosses the axes. The x-intercept has y=0, and the y-intercept has x=0. These are common but not the only important points on a line!

What's the difference between 'passes through' and 'intersects'?

+

'Passes through' means the line goes exactly through that point anywhere on the graph. 'Intersects' usually refers to where the line crosses the x-axis or y-axis specifically.
