Slope
what the slope of this equation? y=3x-10
3
whats another name for systems equations?
multiple step equations
If a graph has a point of 3/1 and its constant, what's the coordinates of the next point?
6/2
if a table start with x=0 and y=0, is it proportional?why or why not?
The table is proportional because it started at (0,0) which is one of the rules for something to be proportional.
what the slope equation?
y=mx
what is a slope and how is it determined?
a slope is a constant a rate at which something going at and is determined by dividing rise over run (vertical distance over the horizontal).
Inverse operation
How is graph proportional or not?
Starts at (0,0) and has a constant pattern.
Can you use a table to represent an equation?
yes
true or false?
Equations are used write a situation
true
how is the slope formula written?
m=y2-y1/x2-x1
solve for d? 12d-11=1
d=1
If the line on a graph is from up to down or right to left, what kind of slope is it?
negative
If a table has one inputs matching to more than one output, is it a function or not?
Not a function
Slope equations with y-intercept form?
y=mx+b
how do you write these two coordinates in slope formula to find the slope? (2,6) (10,30)
30-6/10-2
what the word when you sub a number in for a variable? Hint: sub
substitution or substitute
If a graph has a line going from left to right (down to up), out of the 4 slope, which one is it?
positive
If a table has two points like (4,12) (6,18), what's the slope?
slope: 3
if there's parenthesize in an equation, what's the first step to solving the equation? Hint: dis
distribute
Find the slope from these two coordinates
(3,6) (9,36)
slope= 5
solve x
37=-3+5x+30
x=2
if an equation is written like this y=2/1x+8, where should the first point of this equation be on the graph?
(0,8) because its the y-intercept
How do you know if a table is a function?
if each input match to one output
write the correct equation with this info. i started going to school with 20 pencils, each week i lose 2
y=-2/1x+20
