Given : the distance between two points m and n on a graph is given as √10² + 7²
the point of m are -4,3
and n points lies in first quadrant
To find : all possible x coordinates of point
Solution:
Distance between points (a , b) and ( c , d) is given by
√(c - a)² + ( d - b)²
m ( - 4 , 3) and n ( x , y)
Distance = √ (x - (-4))² + ( y - 3)²
= √ (x+4)² + ( y - 3)²
√10² + 7²
x + 4 = ±10
=> x= 6 , - 14
Hence x coordinate value is 6 as in 1st Quadrant x is +ve
x + 4 = ±7
=> x = 3 , - 11
Hence x coordinate value is 3 as in 1st Quadrant x is +ve
so possible value of x coordinates of point are 3 or 6
