MULTIPLE CHOICE QUESTION

How would I graph the point (-1, 3)?
Hint: (x,y)
Left 1, up 3
Left 1, down 3
Down 1, Right 3
Down 1, Left 3
Answer explanation
(-1,3)
x = -1 x is negative, so you would first go left 1
y = 3 y is positive, so then go up 3
Then plot your point at (-1,3)

MULTIPLE CHOICE QUESTION

Hint: Equations are in SLOPE INTERCEPT FORM: ,
where m represents the SLOPE (aka constant rate or rise/run),
b is the y-intercept (the point where the line crosses the y-axis) and
x and y are points on the line (x,y).
Method two:
PLUG IN the points on the graph (x,y) into each equation to see which equation works (equal on both sides).
y = 3x + 2
y = -2x + 3
y = 2x + 3
y = -3x + 2
Answer explanation
Points from graph that were used to check for correct equation.
(0,3), (1,5), (2,7)
y = 2x + 3
(0,3) y = 2(0) + 3
y = 3
(1,5) y = 2(1) + 3
y = 2 + 3
y = 5
(2,7) y = 2(2) + 3
y = 4 + 3
y = 7

MULTIPLE CHOICE QUESTION

What is the slope (constant rate) in the equation y = mx + b for the table shown. Hint: change in y values/ change in x values
1/2
4/1
-1
1
Answer explanation
The slope (aka constant rate) is 1.
You can either find the slope by
Finding the constant change for y and x
on the table (see image)
You can also pick 2 points from the table
and subtract the y values in the top and
the x values in the bottom.

What is the y-intercept or b in the equation y =mx + b? Hint- this is where it crosses the y-axis.
5
1
0
6
Answer explanation
y intercept is 5 because x = 0 and it crosses the y-axis at (0,5)
