We can use the points on a graph of a linear relationship to write an equation for the relationship. The equation of a linear relationship is y = mx + b, where m is the rate of change, or slope, and b is the y-intercept (The value of y when x is 0).

To check if a given value is a solution to an equation: Evaluate the left-hand side expression at the given value to get a number. Evaluate the right-hand side expression at the given value to get a number. See if the numbers match.

BecauseMoreMinus 10 which is also 14. It checks I know that x equals 3 was a solution to my equation. Because the left side equaled the right side when I substituted it back in.

Find The Equation Of A Line : Example Question #1 Then, plug the slope into the slope formula, y = mx + b, where m is the slope. Plug in either one of the given points, (5, 8) or (2, 6), into the equation to find the y-intercept (b). Plug in both the slope and the y-intercept into slope intercept form.

That's 12MoreSo let's start over on the left-hand side I've got 4 times 3 cuz I'm multiplying first. That's 12 plus 2 and that equals I'm going to go over to this side now and simplify a step 8 times 3 is 24.

Now negative 3 times negative 3 is 9.MoreSo we get negative 3 times negative 3 plus 4 is equal to 13. Now negative 3 times negative 3 is 9. And we'll just recopy everything else down here 9 plus 4 is 13 which does in fact equal 13.

The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term. It is an equation of degree one, with variables x and y. The values of x and y represent the coordinates of the point on the line represented in the coordinate plane.
