A straight line passes through points (1, 15) and(5, 3) What isthe equation of the line?Select one:A) y = - 3x + 18B) y = – 7x + 18C) y = 2x + 18D) y = 3x + 18

Sagot :

Points (1,15) and (5,3)

Find the slope (m)

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

where:

(x1,y1) = (1,15)

(x2,y2) = (5,3)

Replacing:

[tex]m=\frac{3-15}{5-1}=\frac{-12}{4}=-3[/tex]

the function has a slope m= -3

slope intercept form:

y=mx+b

Where

m= slope

so, the correct function is

y=-3x+18 (A)
