Answer :
For every change of x by 1, y increases by 5.
So the gradient of the line is 5.
To find the y-intercept:
y = mx + c
2 = 5(1) + c
2 = 5 + c
c = -3
So the equation of the line is y = 5x - 3
So the gradient of the line is 5.
To find the y-intercept:
y = mx + c
2 = 5(1) + c
2 = 5 + c
c = -3
So the equation of the line is y = 5x - 3
