Q. A line has a slope of 21 and a y-intercept of −23. Write its equation in slope-intercept form.
Identify Linear Equation Form: Identify the slope-intercept form of a linear equation.The slope-intercept form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.
Insert Given Values: Insert the given slope and y-intercept into the slope-intercept form.We are given the slope m as 21 and the y-intercept b as −23. Substituting these values into the slope-intercept form, we get y=(21)x+(−23).
Simplify Equation: Simplify the equation if necessary.In this case, the equation y=21x+(−23) is already in its simplest form, so no further simplification is needed.
