if I you two points can you find; slope, and b, and write the line equation (2,3) (4 , 6))

Question

if I you two points can you find; slope, and b, and write the line equation (2,3) (x2 y2)

Answer 1

Slope=(difference of y values)/(difference of x values)=(6-3)/(4-2)=3/2, so y=3x/2+b where b is found by plugging in one point. Let's use (2,3): 3=3+b, so b=0 and y=3x/2, the line equation. CHECK: Plug in (4,6): 6=3*4/2=6, which is true.

Answer 2

2 points make a line...(2,3) & (4,6)

deltax=2

deltay=3

slope=3/2, line=(3/2)x+sumthun

gotta go thru (2,3), (3/2)*2+sumthun=3

3+sumthun=3

sumthun=0
