Answer:

#(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.
