Write down the equation of a line whose slope is 2 and crosses the y-axis at (0,-3).
alexgriva [62]

The equation of the line is y=2x-3.

It is required to find the equation of the line.

<h3>What is straight line?</h3>

A straight line is just a line with no curves .The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

Given:

The slope-intercept form of a line is

y = mx +c

where c is the intercept and m is the slope.

According to given question we have,

slope =2

y - intercept=-3

The equation of the line

y=2x-3

Therefore, the equation of the line is y=2x-3.
