y = -5 You would substitute the given values for m and b. Simplify if necessary

What Does it mean?

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable.

Slop-Intercept Form

Objectives

Write a linear equation in slope-Intercept form.

Graph a line using slope-intercept form.

Slope-Intercept Form

Graph the line with the slope -2 and y-intercept 4.

Step 1: The y-intercept is 4, so the line contains (0,4). Graph (0,4).

Step 2: Slope = Rise over Run so it would be -2 over 4

Count down two units down and 4 unit to the right from (0,4).

Step 3: Draw a line through the two points.

Slope-Intercept Form

Who invented the slope-Intercept Form

Slope intercept form (y = mx + B) author is really unknown. However there are written text dated back to 1757 that explain the equation referenced as the slope intercept form.

Slope-Intercept Form

Write the equation in slope-intercept form

Graphing by Using Slope and y-intercept.

slope "m" = 3/1= 3

y - y1 = m(x - x1)

We know m now, and also know that (x1, y1) = (3,2), and so we have:

y - 2 = 3(x - 3)

That is a perfectly good answer, but we can simplify it a little:

y - 2 = 3x - 9

y = 3x - 9 + 2

y = 3x - 7
