Hello,
The correct answer is 4... This is the correct exact answer
Answer: do you mean, “if you have the y-int, what else do you need to write an equation?”
If that’s what you mean then you need the slope
Step-by-step explanation:
The point (4,y) has a known x coordinate of x = 4. The y coordinate is unknown right now so we'll just call it y.
Draw a vertical line (see side note below) through 4 on the x axis. I've done so in red (see attached image). The red line crosses the graph at the point (4,1) so this tells us that
y = 1Answer: y = 1
Side Note: you don't have to draw a vertical red line but it's handy to see how it works out. After you get used to these types of problems, you can visually be able to see the answer without these extra lines.
The answer is 69 dollars and the titian would be 69 dollas
