Write the equation of a line with a slope of 4 and a y-intercept of -2.
Use the form 𝑓(𝑥) = 𝑚𝑥 + 𝑐.
Find the x-intercept of the line 𝑦 = 5𝑥 - 10.
Set 𝑦 to 0 and solve for 𝑥.
What is the slope of a line that rises from left to right?
Think about how the line moves.
True or False: The y-intercept is found where a line crosses the x-axis.
Remember the definition of intercepts.
Create a linear equation that models a situation where a phone plan costs $20 per month plus $0.10 per text sent. Represent it as an equation and identify the slope and intercept.
Consider the components of the cost equation.
