Question

A line of gradient 7\9 passing through the points q(3,4) cut through the y-axis at a point p.find the condinates p

Answer 1

Slope of the line = (7–3)/(4–2)=2. It’s eqn: y =2x + k and it passes through (2,3). Thus, 3 =2*2 + k or k = -1. The line: y = 2x - 1. At x=0, y= -1. Then A: (0,-1)
