Linear Relationships

Is this table proportional or non-proportional?

On DESMOS Use y1~mx1+b

Then insert table with points

• Proportional

• Non-Proportional

Tags

CCSS.7.RP.A.2B

Write the equation for the table given.

On DESMOS Use y1~mx1+b

Then insert table with points

(slope or "m" is always next to a letter and y intercept or "b' is always alone)

• y = 1/3x

• y = 3x

• y = 1/2x

• y=x

CCSS.8.F.B.4

CCSS.HSF.LE.A.2

Identify the constant of proportionality (K or m)

Use Desmos

y1~mx1+b

Then insert table with 2 points

• k = 5

• k = 1/5

• k = 1

• k = 2.5

• none (not proportional)

CCSS.7.RP.A.2B

This equation does not show a proportional relationship. Why?

• Doesn't go through point of origin (0,0)

• Not a straight line

CCSS.7.RP.A.2D

Is the graph proportional or non proportional?

• proportional
• non proportional
