I also need to know how to graph it....

Example: y = 3x + 2
Slope: 3
y-intercept: 2
How to graph: Start at point (0, 2) on an x,y-graph. That's your first point. If your y-intercept was -4 instead, then you would start at point (0, -4). Move 3 units up, then 1 unit to the right (that's your slope: 3, which is equal to 3/1). That makes your second point (1, 5). To get your third point, again go 3 up, then 1 to the right. Your third point is (2, 8). When using the slope to find the next point, you always use the numerator of the slope to move along the y-axis and the denominator of the slope to move along the x-axis.

the initial case is the intercept equation
for a curve when x= 0 f(x) = y = c the intersept
for a curve when x= 0 f(x) = y = c the intersept

Solve for y. Then plug&chug to plot
