Answers
y=mx+b - CORRECT ANSWER- ✔✔Slope-Intercept Form
m - CORRECT ANSWER- ✔✔slope
b - CORRECT ANSWER- ✔✔y-intercept
Y2-Y1/X2-X1 - CORRECT ANSWER- ✔✔slope formula
Definition of a relation - CORRECT ANSWER- ✔✔Any set of ordered pairs
X-values can repeat; fails the Vertical Line Test when graphed
Definition of a function - CORRECT ANSWER- ✔✔A relation where each x is paired with
exactly one y
No x-values repeat; passes the Vertical Line Test when graphed
What's the short cut for recognizing a function in ordered pair form? - CORRECT ANSWER-
✔✔If you notice that there is an x value repeated with a different answer for the y value
How do you use the vertical line test to tell if a graph is a function? - CORRECT ANSWER-
✔✔As the vertical line passes over the graph, the vertical line can only intersect the graph
one time
Slope is the ratio of ____ over ___ - CORRECT ANSWER- ✔✔Rise, Run
What is the slope of a horizontal line? - CORRECT ANSWER- ✔✔0
, What is the slope of a vertical line? - CORRECT ANSWER- ✔✔Undefined
How do you solve a system of inequalities to find the solution? - CORRECT ANSWER-
✔✔Graph the inequalities and find the area where the shading overlaps. In the shaded area,
every point is a solution to the system of inequalities.
What is the standard form of a line? - CORRECT ANSWER- ✔✔Ax+By=C
When will a system have infinitely many solutions? - CORRECT ANSWER- ✔✔Same line
(coinciding lines)
If you are given a point and a slope, explain one way used to find the equation. - CORRECT
ANSWER- ✔✔Substitute the x, y, and m into point-slope formula and rewrite equation in
slope-intercept form.
When will a system have no solution? - CORRECT ANSWER- ✔✔Parallel lines
What should the answer to a system look like? - CORRECT ANSWER- ✔✔An ordered pair
(intersection point)
What are some ways to solve a system? - CORRECT ANSWER- ✔✔Graphing, Substitution,
and Elimination
For linear inequalities, if it is greater than, where do you shade? Less than? - CORRECT
ANSWER- ✔✔Greater than=shade above, Less than=shade below
What is true about the slopes of parallel lines? Their y-intercepts? - CORRECT ANSWER-
✔✔Parallel lines have the same slopes, but different y-intercepts
What must you do if you multiply or divide both sides of an inequality by a negative number?
- CORRECT ANSWER- ✔✔Change the inequality sign
