Question

What is the gradient and y intercept of the following lines 1) y= 2X + 3 2) y = 5X + 1 3) y= 3X + 2

Answer 1

see explanation

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope( gradient ) and y the y- intercept )

The 3 equations are in this form

(1)

y = 2x + 3

with gradient = 2 and y- intercept = 3

(2)

y = 5x + 1

with gradient = 5 and y- intercept = 1

(3)

y = 3x + 2

with gradient = 3 and y- intercept = 2
