Linear Equations

Have you ever noticed how some roads are steep while others are almost flat? In math, we use slope to describe how steep a line is. Slope helps us und

Have you ever noticed how a road goes uphill, downhill, or stays flat? In math, we use slope to describe how steep a line is. Slope helps us understan

Have you ever compared prices at a store or checked your speed while riding a bike? These situations use unit rates. A unit rate compares two quantiti

A proportional relationship happens when two quantities change at the same rate. Graphing a proportional relationship helps us see how the quantities

Have you ever noticed that some things increase at a steady rate, such as the cost of movie tickets or the distance traveled at a constant speed? Thes

Proportional relationships can be represented in different ways. Two common representations are equations and graphs. Both show the same relationship,

Similar triangles have the same shape but may have different sizes. One triangle can be larger or smaller than another while still being similar. Simi

The slope of a line describes how steep the line is. It compares the vertical change, called the rise, to the horizontal change, called the run. Using

Solving equations often requires finding the value of a variable. To do this, we use inverse operations to undo operations and isolate the variable. I

Have you ever noticed that some things increase at a steady rate, like earning points in a game or saving money each week? The equation y = mx helps u

Many real-world situations involve a starting amount and a constant rate of change. For example, a taxi ride may have a starting fee plus a cost for e

Have you ever needed to figure out an unknown value, like how much money someone spent or how many points a team scored? Linear equations help us solv

A system of equations is a set of equations that uses the same variables. When solving a system, we look for values that make all the equations true a

Linear equations help us find unknown values. Sometimes, when we solve a linear equation, we get one answer. Other times, we find that no value can ma

Linear equations help us solve problems where an unknown value needs to be found. They are often used in everyday situations involving money, distance

Linear equations can help us find unknown values in everyday situations. By using mathematical operations, we can determine a missing quantity and sol

Linear equations can help us compare different situations and find when two quantities are equal. This is useful when comparing prices, plans, or cost
