New cards

Positive Slope (uphill)

Left to Right

<p>Left to Right</p>
2
New cards

horizontal slope

equals 0 or 0/a

<p>equals 0 or 0/a</p>
3
New cards

How to find slope

M= rise over run TIP (find two points on the graph, Start from the LEFT)

<p>M= rise over run TIP (find two points on the graph, Start from the LEFT)</p>
4
New cards

Slope intercept form

y=mx+b
m= slope
b= y-intercept

<p>y=mx+b<br>m= slope<br>b= y-intercept</p>
5
New cards

Parallel Lines

Lines never intersect same slope different y intercepts

<p>Lines never intersect same slope different y intercepts</p>
6
New cards

Perpendicular lines

Lines that intersect to form right angles/ Slopes are Opposite reciprocals CHANGE SIGN THEN FLIP THE NUMBER

New cards

What is slope?

The steepness of a line the average rate of change.
M= change in y/ change in x or rise/run or Distance/ time

8
New cards

Negative slope (downhill)

Right to left

<p>Right to left</p>
9
New cards

Vertical slope

undefined Tip (check in the calculator shows that it can't be solved)

New cards

Point Slope form

y-y1=m(x-x1)

<p>y-y1=m(x-x1)</p>
11
New cards

Equation of a Horizontal Line

Find the slope ex: 0/2=0 the equation would be the y value

12
New cards

Equation of Vertical line

No slope since it would be undefined the equation would be the x value
