Question

what is the y-intercept of the line that goes through the points (6,14) and (18,8)?

Answer 1

over twelve down six slope is
\[-\frac{1}{2}\]

Answer 2

now use almighty point slope formula
\[y-y_1=m(x-x_1)\] with \[x_1=6,y_1=14, m=-\frac{1}{2}\]

Answer 3

first lets write the equation first
y=mx+b
we need m and b
\[m=\frac{ \Delta y}{\Delta x}=\frac{8-14}{18-6}=\frac{-6}{12}=\frac{-1}{2}\]
y=-1/2*x+b
we know a point on this line (x=6,y=14)
14=-1/2*6+b
14=-3+b
17=b
y=-1/2*x+17
y intecept is b=17
x intercept (let y=0 solve for x) 0=-1/2*x+17
17=1/2*x
2*17=x
34=x
