Answer:
y = x + 11
Step-by-step explanation:
The equation of a straight line is: y = mx+c where m is the slope of the line and c is the y-intercept of a line.
Slope =
=
=
=
To find the y-intercept, we can use one of the points to apply for the equation before finding the y-intercept. I will be using the point (4,14).
y = x + c
14 = ×4 + c
14 = 2 + c
c = 14-2
c = 11
Thus, the y-intercept is 11.
