Question

James walks to a coordinate of (4, 5) and then to (1, 2) which joins the two coordinate in a straight line.Find the: (i) Gradient (m) of the line joining the two points. (ii) Equation of the line joining the two points.​

Answer 1

gradient = slope = 1

Y =1X +1 is the equation

Explanation:

x1 y1 x2 y2

4 5 1 2

(Y2-Y1) (2)-(5)= -3 ΔY -3

(X2-X1) (1)-(4)= -3 ΔX -3

slope= 1

B= 1

Y =1X +1
