1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t
Answer:
y = -1/3x +3
Step-by-step explanation:
When given a point and slope, it is convenient to start with a point-slope form of the equation of a line.
y = m(x -h) +k . . . . . line with slope m through point (h, k)
y = (-1/3)(x -3) +2 . . . line with slope -1/3 through point (3, 2)
y = -1/3x +3 . . . . . . . simplified to slope-intercept form
Answer:
<h2>
y=0.25x+1</h2><h2>
or </h2><h2>
y=(1/4)*x+1</h2>
Step-by-step explanation:
the slope intercept form is y=mx+b, where m is the slope and b is the y-int
plug in the slope:
y=(1/4)x+b
y=0.25x+b
now plug in the point's coordinates (x,y) to solve for b or the y-int
2=0.25*4+b
2=1+b
1+b=2
b=2-1
b=1
now plug in 1 for b in the equation:
y=0.25x+1
or
y=(1/4)*x+1
