Freddy reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks:
Which equation best models the relationship between x and y?

y = −5x + 40
y = −40x + 280
y = −40x + 200
y = −5x + 200

Wow, the only thing i can think of is that it gives you y and x, so you're basically plugging in the other numbers. So y = 200 and x = 5, and if you were to plug those numbers into each equation they give you, you would come up with 15, 80, 0, and 175. But you're trying to get y to equal 200, so the closest one is c. I'm sorry that's the only thing i can come up with. The rest just aren't close.

The linear equation that best models the relationship between x and y is y = -40x + 200.

What is the graph of a linear equation?

The graph of a linear equation is a straight line graph and the function of a linear equation assumes a slope-intercept form y = mx + b

where;

  • Slope = m
  • y-intercept = b

The slope = rise/run

From the graph, we need to rise 200 units to the origin and run 5 units to the horizontal positive axis.

So,

  • Slope = -200/5
  • Slope = -40

The y-intercept is the region at which the line cuts the vertical axis.

  • y-intercept = (0,200)

Now, putting it all together and using the slope-intercept form, the equation that best models the relationship between x and y is:

y = -40x + 200
