Question

Determine the slope (m) and y-intercept (b) of a line that passes through the points (2,9)

and (5,21). Use a table with at least three other points and draw a graph to justify your answers. Finally, construct a
story problem that would use these conditions in the real world.

Answer 1

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept. x and y represent the distance of the line from the x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is.
