Graphing from Points and Tables

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)

• 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

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)
