Question

Irfan incorrectly determined that the equation for the line on the graph is y = 0.5x +5. What is the correct equation for the line?

Answer 1

y=-1x+0.5

Explanation:

First calculate the slope of the line=y2-y1/x2-x1

Take any two points

1-3/2-1

-2/1

slope=-1

y=mx+c (equation for line)

Take any point and figure the value of c

1=-1x2+c

1/-2=c

c=0.5

y=-1x+0.5
