Question

What is the equation of the line passing through (0,8) and (4,0)

Answer 1

Answer:

y= -2x + 8  or y= -2/1x + 8

Step-by-step explanation:

So first you would do the slope formula

m= y2-y1/x2-x1

m= 0 - 8 / 4 - 0

It does not matter which is x1 and x2, or y2 and y1.

Subtract and you will get: -8/4...

then simplify: -8/4 divided by 4 = -2/1 <<That's your slope

plug it into the equation: y=mx+b

y=-2/1x + b

plug in one of the points into the formula (does not matter which)

8=-2/1(0)+b

solve for b

b=8

so the formula is

y= -2/1 x + 8

or

y= -2x + 8
