4. Find the equation of the line going through the points (-1,2) and (2,5) 5. Find the slope and y intercept of the line whose equation is -+--3 6. Find the equation of the line going through the point1 and perpendicular to the line 2x+5y 3 Dr. Oz owns $1,500 worth of medical equipment which, for tax purposes, are assumed to depreciate linearly to zero over a 10 year period 7. a. Express the value of the doctor's equipment as a function of time b. What is the value of the equipment after 4 years?

Explanation / Answer

Solution4:

eqaution of two point form of a line is

y-y1=m(x2-x1)

where m=slope=y2-y1/x2-x1

therefore

m=5-2/2-(-1)

=3/2+1

=3/3

=1

therefore equation of line

y-2=1(x-(-1))

y-2=x+1

y=x+1+2

y=x+3 is the equation of line
