Answer:

Explanation:

(3,0),(4,1) ⇒ (x₁,y₁),(x₂,y₂)

to find the equation of the line

y-y₁= {(y₂-y₁)/(x₂-x₁)}(x-x₁)

y-0= [(1-0)/(4-3)] (x-3)

y-0 = 1/1(x-3)

y-0 = x-3

y= x-3+0

y=x-3

compare to y=mx+c, where m is the gradient and c is the intercept on y-axis

m=1, c=-3

∴the y-intercept of the line is -3
