The slope-intercept form of a line is y = mx + c, where m is the slope and c is the y-intercept.
What is the y-intercept of the line y = 2x - 5?
Show answer
-5
In the equation y = mx + c, c is the y-intercept. Here, c = -5, so the y-intercept is -5.
The equation of a line with slope 3 and y-intercept 2 is:
Show answer
y = 3x + 2
Using the slope-intercept form y = mx + c, with m = 3 and c = 2, the equation is y = 3x + 2.
