Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s 2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line .
What will be the equation of straight line? Solution: We can calculate the equation using point slope form with the above given formula. Substituting the values in the formula, (y - 5) = 5(x- 7) y - 5 = 5x - 35 y - 5x = -35 + 5 y - 5x = -30 5x -y -30 = 0 is the equation of the straight line.

Free 5e solo adventuresSystems of linear equations are groups of more than one linear equation. Solving the system refers to finding a solution common to all of the linear equations in the systems. There are only three possibilities: 1) The system has one unique solution (a consistent system) 2) The system has infinitely many solutions (also a consistent system) 3 ... These lines are written in the form y = mx + b, where m is the slope and b is the y-intercept. We know from the question that our slope is 3 and our y-intercept is –5, so plugging these values in we get the equation of our line to be y = 3x – 5. m = 3 and b = –5
