Can you teach me how to determine the slope using the equation below?
y=6x+3

recall the sloe-intercept form of a line:

y = mx+b

where m is the slope.

slope is defined as the change in y, divided by the change in x.

Since y=6x+3, y changes by 6 whenever x changes by 1. For, consider

y(x) = 6x+3
y(x+1) = 6(x+1)+3 = 6x+9

x has changed by 1, and y has changed by 6. The slope is 6/1 = 6
