Question #5a48c

Answer 1

`(0,-1),(4,0)`

Explanation:

When this line crosses the y-axis the corresponding x-coordinate at this point will be zero. Substituting x = 0 into the equation of the line will give the value of the y-coordinate.

`rArry=(0.25xx0)-1=0-1=-1`

`rArr(0,-1)" is point on the y-axis"`

Similarly when the line crosses the x-axis the corresponding y-coordinate at this point will be zero. Substituting y = 0 into the equation gives the value of the x-coordinate.

`rArr0.25x-1=0rArr0.25x=1`

`rArrx=1/(0.25)=4rArr(4,0)" is point on the x-axis"`

`"Plot (0,-1),(4,0) "` on square paper and draw a straight line through them.
