Solving linear equations easy
WebExample 1Solve: 3a + 4 = 19. This equation says 3 times a plus 4 is equal to 19. We need to find out what number a is, to do that we need to get a by itself. The first step is to get rid of the 4. The opposite of adding 4 is subtracting 4. To keep both sides of the equation equal we need to subtract 4 from both sides of the equation. WebTo find the slope use the formula m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line. The y-intercept is the point at which x=0. What are the 4 methods of …
