Answer:
y= 3x + 3
Step-by-step explanation:
From the graph we get 2 points: (-1,0) and (0,3)
(0,3) tells us that b = 3
and we use the equation to calculate m
m = = 3/1 = 3
so plugging m and b into y = mx + b gives us
y = 3x + 3
The figure shows the height, h, of a thrown ball as a function of time. Height is measured in feet and time is measured in secon
ds. How long will it take for the ball to return to the ground? 40 30 Height in Feet 20 10 1 2 3 4 5 Time in Seconds A 2.5 seconds C 5.0 seconds B 3.5 seconds D 35.0 seconds

x + y = 15 and 5x + 10y = 100 are the system of equations that represent this situation
<em><u>Solution:</u></em>
Let "x" be the number of multiple choice questions
Let "y" be the number of short answer questions
Worth of 1 multiple choice questions = 5 points
Worth of 1 short answer question = 10 points
<em><u>Ms. Lee wrote a test with 15 multiple choice short answer questions</u></em>
Therefore,
number of multiple choice questions + number of short answer questions = 15
x + y = 15 -------- eqn 1
<em><u>The maximum number of points possible on the test is 100</u></em>
Therefore, we frame a equation as:
number of multiple choice questions x Worth of 1 multiple choice questions + number of short answer questions x Worth of 1 short answer question = 100
5x + 10y = 100 ------- eqn 2
Thus eqn 1 and eqn 2 are the system of equations that represent this situation

3y = 4x + 39
y = +
When x is 0, y = 0(x) + , so the y intercept is
So can be rearranged to
, so the slope would be
