Question

Given that A(2, 1) and B(9, 25) are points on a graph. USE THIS INFORMATION TO ANSWER QUESTIONS 14 TO 16

Find the length of the line joining the two points
Find the gradient of the line joining the two points.
Find the equation of the line drawn from these points

Answer 1

Answer:

required answer:-

• A (2,1)
• B (9,25)

${:}\leadsto$$\sf AB=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2}$

${:}\leadsto$$\sf \sqrt {(9-2)^2+(25-1)^2}$

${:}\leadsto$$\sf \sqrt {(7)^2+(24)^2}$

${:}\leadsto$$\sf \sqrt {49+576}$

${:}\leadsto$$\sf \sqrt {625}$

${:}\leadsto$$\sf AB=25cm$
