Question clarified:
The slope tells you how much the y-value of a point changes each time the x-value increases by 1 unit. This is called the ____________ (1).
When one quantity changes at a ____________ (2) rate relative to another, there is a ____________ (3) relationship between the quantities, which is graphed as a ____________ (4).
Some basic explanation:
Line is a points connected that goes in both directions infinitely. Basically:
It has slope. Which is the rate of change of y with respect to x.
Line is a linear curve.
Now, the first part tells us the rate of change of y with x, so blank (1) would be rate of change.
Let's look at the second part now:
When y and x changes at a constant rate (constant slope), it will be a line. Otherwise, it is a curve.
Hence, blank (2) is "constant".
The relationship is linear, that is blank "3".
Of course, when graphed, it creates a "line".
That's blank number 4.
Final answer:
The slope tells you how much the y-value of a point changes each time the x-value increases by 1 unit. This is called the rate of change (1).
When one quantity changes at a constant (2) rate relative to another, there is a linear (3) relationship between the quantities, which is graphed as a line (4).
