What is a slope? i forgot everything cause it’s friday..

It’s a number that describes both the direction (positive or negative) and the steepness of the line. It’s usually denoted by the letter m. Informally, the slope of a line is found with the catchy phrase “rise over run“. This works with any segment, of any length, for any straight line:

1) Find the rise (the length of a segment on the y-axis): The rise (the length of the vertical blue line) in the above picture is 4.

2) Find the “run” (the length of a segment on the x-axis): The run (the length of the horizontal blue line) is 2.

3) Divide the rise (Step 1) by the run (Step 2): 4/2 = 2.

The slope for this example is 2.

The formula for a straight line is:  y=mx+b

Where:

b = the y-intercept (where the graph crosses the y-axis),

m = the slope (i.e. how steep the line is),

x = a variable.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

constants mean the stopped points or the points on a graph that nothing is changing, hope this
