How Do You Find Slope From The Equation For A Line?
Find the slope of a line from it’s equation in just two easy steps. This free math help will literally allow you to read the slope from the equation, and as a bonus, will allow you to read off the y-intercept of a line, too. Express your equation in slope-intercept form. The way you do this is by solving for y so that your equation looks like y = mx + b. This is “slope intercept form.” Let’s start with an example: 6x + 3y = 9. This equation is not in slope intercept form yet. To get there, we solve for y: 6x + 3y = 9 , we subtract 6x from both sides 3y = -6x + 9 , we need to solve for y so we divide both sides by 3 y = -2x + 3 , this is the equation in slope-intercept form! Read off slope from the slope-intercept form equation. Honestly, this is really, really easy. Slope intercept form for a line is y = mx + b where m is the slope and b is the y-intercept. To find slope just read off what number is being multiplied by x and that is the slope. In our example, the slope is -2, or stated
