What is slope and how is it determined from a graph? How do you determine the intercepts from an equation or graph? How can linear equations and functions be written and graphed?

    to find the slope they give you an equation AND ALL YOU HAVE TO DO IS PLUg IN THE coordinates sorry accidentely put all caps

    the slope is rise / run for a straght line |dw:1438107692093:dw|

    if a line joins 2 points (x1,y1) and (x2,y2) the slope = y2 - y1 ------ x2 - x1

    intercepts to find intercept on y axis for y = 3x + 2 - they occur when x = 0 so for this equation intercept is y = 3(0) + 2 = 2 to find the x intercepts put y = 0 and solve for x

    one form of a linear equation is the slope-intercept one y = mx + b where m = slope and b = y-intercept knowing these 2 values you can draw the line of the equation

    another form , very useful , is the point-slope form y - y1 = m (x - x1) m = slope and (x1,y1) is a point on the line
