## What is a system with exactly 1 solution?

A linear system that has exactly one solution is called a consistent independent system. Consistent means that the lines intersect and independent means that the lines are distinct.

## What is a system in algebra?

A “system” of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.

## What is a linear system in math?

In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same set of variables. For example, is a system of three equations in the three variables x, y, z.

## How do you find MX B?

Step 2: Use the formula y = mx + b to determine the y-intercept, b. Replace x and y in the formula with the coordinates of one of the given points, and replace m with the calculated value, (2). Find the equation of the line whose graph contains the points (1,–2) and (6,5). The answer will look like y = mx + b.

## What is Y MX B word problems?

In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.

## What is y mx b example?

If the slope ‘m’ and y-intercept ‘b’ are given, then the equation of the straight line can be written in the form of ‘y = mx +b’. For example, if the slope(m) for a line is 2 and the y-intercept ‘b’ is -1, then the equation of the straight line is written as y = 2x – 1. The slope value can be positive or negative.

## What is the real life meaning of the Y-intercept?

Just like the slope of a line, many algebra classes go over the y-intercept of a line without explaining how to use it in the real world. The y-intercept of a line is the value of y where the line crosses the y-axis. In other words, it is the value of y when the value of x is equal to 0.

## Why is the Y-intercept called B?

The nifty thing about this equation is that the number next to the x (in this case a) is the slope – or the measurement of how much the line tilts. Turns out that the b here is also exactly where the line smacks into the y-axis – AKA the y-intercept. But there’s no fancy letter for that, so we just leave it as b.

## Why is it M in Y MX C?

Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis). It cuts the y-axis at -2, and this is the constant in the equation. …
