Graph the line using a point and a slope. write the equation of each line. b a line that passes through the point (4, 0) and whose slope is 0.5.

The line passes through (4,0)

And has a slope of 0.5

Taking another point (x,y) along the line;

Slope = change in y-axis ÷ change in x-axis

0.5 = (y - 0) / (x - 4)

y = 0.5x - 2

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

529 and 531
