Question 1

What is the Distance Formula?

Answer 1

The distance formula can be used to find the distance between two points on a graph by substituting the numbers.

Question 2

What is the slope formula?

Answer 2

The slope formula can be used to calculate a line’s inclination or steepness. It can be used to calculate the slope of any given line by dividing the change in y over the change in x

m = (y2-y1) / (x2-x1)

Question 3

What is Point-Slope Form?
What is it’s purpose?

Answer 3

y − y1 = m(x − x1)

where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line

to describe the equation of the entire line when given a point on the line and the slope.

Question 4

Slope-Intercept Form?

Answer 4

y = mx + b

where m is the slope of the line and b is the y intercept

used to find the y-intercept and the slope of a straight line.
