The equation of a line can be determined if only the slope and the x intercept are known.

Question

Quizplus · Accepted Answer

An equation of a line can be written in the form y = mx + b, where m is the slope and b is the y-intercept. If we know the slope (m) and the x-intercept (a,0), we can substitute these values into the equation y = mx + b and solve for b. For example, if the slope is 2 and the x-intercept is (3,0), we can write y = 2x + b and substitute 3 for x and 0 for y to get 0 = 2(3) + b, which simplifies to b = -6. Thus, the equation of the line is y = 2x - 6.
