How To Do Linear Equations? - Answers

Linear equations (sometimes called Linear Functions) are done using the general form y = mx + b y represents your y-axis value at a certain point m represents the slope of your line (how steep or how gentle it is) x represents the x-axis value at the same point as y b represents the y-axis intercept (where your line crosses the y-axis Given the example y=3x + 1: the m (slope) in this case is 3 the b (y-intercept) is +1 x and y will change for each point on this line. Since our 'b' is 1, we know that the point (0,1) is on our line. So, it can be said that 1 = 3(0) + 1 instead of y = mx + b Working this out, we have 1=1 (which is true).
