The y-intercept of the line is 32
Step -by -step explanation :
The general form of equation of a line that will pass through the three points is:
y=mx+c
where m is the gradient and c is the y-intercept
Now, find the gradient.
Take,
By substitution,
we now put the values of m, x and y into the general equation to find the c
Hence the y-intercept of the line is 32
