Expression, Equations, and Functions
Write an equation of the line that has a slope of -4 and has a y-intercept of -2
y = -4x -2
What is slope-intercept form, and what does each part represent?
y=mx+b
m is slope
b is y - intercept
How do you find the slope and y-intercept when given the graph of a line?
Slope - Find two points where it crosses in the grid line (exact points) count the rise and then the run.
Y-Intercept - Find where the line crosses the y axis.
