How well do you know the formula chart?(8th grade math)

When the question ask me for the equation that represents a situation, I need the m and the b. What does m and b represent?

• m=slope; b=y intercept

• m=y intercept; b=slope

When I look at a graph, how can I tell the y intercept?

• The point when x = 0; which is also the point where the line touches the y axis.

• The point when y=0; this is also the point where the line touches the x axis

I can calculate the slope of a graph by using rise/run. I can also use...

• $\frac{x_2-x_1}{y_2-y_1}$

• $\frac{y_2-y_1}{x_2-x_1}$

m is the same thing as...

• b=y intercept

• k=constant of proportionality

ONLY IN PROPORTIONAL RELATIONSHIPS, I CAN US_________TO CALCULATE THE SLOPE.

• $\frac{Y}{X}$

• $\frac{X}{Y}$

I can draw a _____________________________ to connect two dots on a line if I need to calculate the slope?

• rectangle

• triangle

• right triangle

The formula for the area of a triangle and rectangle help me to find the surface area of prisms? Which formulas will I substitute B with if I need to find the surface area of a triangular prism?

• $bh$

• $\frac{1}{2}bh$

How will I know that I need to use another formula within a formula?

• The letter in the formula will be capitalized

• The letter will be lower cased

When I need to find the height of a triangular prism in this formula Ph + 2B, I will substitute h with?

• 6

• 7

• 12

 $\frac{1}{2}bh$  When I need to find the height of the triangle for the area of the base using this formula, what is the height of the triangle?

• 6

• 7

• 12
