y=mx+b y0=mx0+b 5=3*2+b b=5-5=0 y=3x+0
It is useful when dealing with very small or very large numbers.
slopeintercept equations are used to find the slope and intercept (obviously lol) they are set up like this y=mx+b m is the slope and b is the y-intercept lets say you have an equation like... 2x + y = 5 (now minus 2x from both sides) 2x - 2x + y = 5 - 2x (simplify) y = 5 - 2x just use algebra to turn the standard form to slope intercept form
A linear equation. It may be written in the form y = mx + c or, more generally, ax + by + c = 0 The first form is useful in two dimensions but the second is more useful for extension from 2 to 3 or more dimensions.
It depends which integer! The website in the related link should help. It was really useful for me ! .
