We are going to explore how to write an equation for a line using the slope and y-intercept. You will also learn how to write an equation using point intercept form.
TEKS Standards and Student Expectations
A(2) Linear functions, equations, and inequalities. The student applies the mathematical process standards when using properties of linear functions to write and represent in multiple ways, with and without technology, linear equations, inequalities, and systems of equations. The student is expected to:
A(2)(B) write linear equations in two variables in various forms, including y = mx + b, Ax + By = C, and y - y1 = m(x - x1), given one point and the slope and given two points
Given two points, the slope and a point, or the slope and the y-intercept, the student will write linear equations in two variables.
Explain how you can create an equation in slope-intercept form when given two points.
Explain how you can create an equation in point-slope form when given two points.
