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.​

gradient = slope = 1

Y =1X +1  is the equation

Step-by-step explanation:

x1y1  x2y2

45  12

(Y2-Y1)(2)-(5)=   -3  ΔY-3

(X2-X1)(1)-(4)=    -3  ΔX-3

slope=1          

B=1          

Y =1X +1    

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
