Question

Write the eq line l 4 1id is perpendicalar to Point A (0,-4) and Point B (4,4) creates a line segment. Point Clies on the line AB. the ratio of line AC to CB is 1:3. What is the coordinate of C? 5. Quadrilateral LMNO has coordinates L(4,5), M(8.7),N(10.11), and 0(6,9).How can quadrilateral LMNO be classified? A. Square B. Rhombus but not a square C. Rectangle but not a square D. Parallelogram but neither a rhombus nor a rectangle E. None of the above 6. Line segment JK in the xy-coordinate plane has endpoints with coordinates (-2,9) and (6.-3) What are two possible locations for point M so that M divides JK into two parts with lengths in a ratio of 1:3? Indicate both locations.

Explanation / Answer

Solving only Q4) as per Chegg rules:

A=(0,-4) and B=(4,4)

Let C=( x, y)

C divides AB in 1:3 ratio

x= (1*4 + 3*0)/(1+3) = 4/4 = 1

y= (1*4 + 3 * (- 4))/(1+3) = - 8/4 = - 2

C=( 1,-2)
