Question

What is the equation of the line which has a gradient of 2 and passes through the point (1,4)

Answer 1

Y= 2x+2

Explanation:

line equation is y=mx +c

m is the gradient = 2

We are given an x and y value

X= 1
y= 4

substitute that into the equation:

4= 2(1) +c

2=c

Put all the equation together:

Y= 2x+2
