-- Look at the places where the line crosses the 'x' axis and the 'y' axis.
Between those two points, it goes forward 2 units, but only rises 1 unit.
So the slope of the line is 1/2 .
-- Look again at the point where the line crosses the y-axis.
At that point, y=1 .
That's the "y-intercept".
Now you have the slope and y-intercept of the line.
The equation of ANY straight line is
y = (slope)x + (y-intercept) .
You know what they both are, so you can easily write
y = 1/2 x + 1 .
Is that one of the choices ?
Yes it is.
Good enough for me.
That must be the correct one.
With no "blah blah blah" required.
<u>burned: </u>756 calories
<u>hours:</u> 3
same number of calories each hour
-> to find this, we must split the number of calories evenly among the hours
<u>steps</u>
756/3
= 252 calories per hour
Answer:
y = 1/2x - 6
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - (-5) / 8 - 2
3 / 6
= 1/2
y = 1/2x + b
-5 = 1/2(2) + b
-5 = 1 + b
-6 = b
