Explanation:
Detailed explanation-1: -For the linear equation y = a + bx, b = slope and a = y-intercept. From algebra recall that the slope is a number that describes the steepness of a line, and the y-intercept is the y coordinate of the point (0, a) where the line crosses the y-axis.
Detailed explanation-2: -In the equation y = a + bx, the constant b that multiplies the x variable (b is called a coefficient) is called as the slope.
Detailed explanation-3: -The equation of a straight line is y=mx+c y = m x + c m is the gradient and c is the height at which the line crosses the y-axis, also known as the y-intercept.
