Question

the coordinates of two points A and B are zero, 4 and 3, 7 respectively find:- 1)-the gradient of ab.
2)-the equation of ab.
3)-the coordinates of the point where the line a b intersect the x-axis.

Answer 1

1) Gradient: (7-4)÷(3-0) = 1
2) Equation: => y-4 = 1 (x-0) => y = x+4
3) Coordinates: Intersects x-axis so y=0 and therefore, => 0 = x+4 therefore, x = -4 so the coordinates are (-4,0)
