In order to find the gradient of the line y = 3x - 7, take a look at the number that appears before 'x'; this number is 3.

Henceforth, the gradient is 3.

Bonus Question:

What is the y-intercept of the line y = 3x - 7

In order to find the y-intercept of the line y = 3x - 7, take a look at the constant term; the term is -7.

Henceforth, the y-intercept is -7.

KEY INFO

This only works for equations that are formatted like y = mx + b, which is slope-intercept (m is the gradient/slope and b is the y-intercept). There are other forms of lines' equations, but the slope is different.

Answer:

gradient = 3

Explanation:

the equation of a line in slope- intercept form is

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

y = 3x - 7 ← is in this form

with gradient m = 3
