Water exists in 3 states: Solid/ice, liquid/drinking water, gas/water vapor. Melting point = freezing point. They both describe the same transition of matter – liquid to solid is freezing and solid to liquid is melting. Freezing point of water — 32 F and 0 C at 1 atm of pressure Boiling point of water —[…]
What does it mean if x and y are directly related (directly proportional)? As x increases, y increases. As x decreases, y decreases. What about inversely related (indirectly proportional)? If x increases, y decreases and vice versa. Example: Carbon emissions and air quality.
If you are trying to measure the impact of a medication on blood pressure readings, you would have a treatment and a control group. The control group includes people who are not given the new medication. The treatment group is given the medication. In a randomized trial, you randomly assign participants to one of the[…]
The independent variable (X) affects the dependent variable (Y). If you measure the effect of tutoring hours (X) on ACT score (Y), tutoring hours is independent variable and the ACT score is the dependent variable. The independent variable is graphed on the x axis and the dependent variable is graphed on the y axis.
Line c passes through (8,-10) and (2,8). Line d is parallel to line c and passes through (6,1). Find the equation of line d.
Line n passes through (12,4) and (-6,10). Line s is perpendicular to line n and passes through (-3,9). Find the equation of line n.
