The equation of this line would be y = 2x - 5
In order to find this, you must first know the formula for slope intercept form. It is written below.
y = mx + b
In this equation, the x and y do not change. The m is the value of the slope (2). The b is the y value of the y-intercept (-5). So, we simply input those numbers in their letter's place to get the final answer.
