Final answer:
To find the equation of a line with two given points, you can use either the point-slope form or the slope-intercept form. The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is one of the given points, and m is the slope. The slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.
Step-by-step explanation:
Slope and y-intercept of a Linear Equation
For the linear equation y = a + bx, b is the slope and a is the y-intercept. The slope is a number that describes the steepness of a line, and the y-intercept is the y-coordinate of the point where the line crosses the y-axis.
