2 answers:
Answer:
320 calories.
Step-by-step explanation:
It is given that a medium sized apple has 70 calories .
This is 10 calories less than 1/4 of the calories in an old westie chocolate bar.
Let the calories in an westie chocolate bar = x
Now we establish an equation and find the value of x
x - 10 = 70
x = 70 + 10
x = 80 × 4
x = 320
An old wetie chocolate bar has 320 calories.

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 = 1
Answer: 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.
