Write a line equation through two points
When to use this goal
For high school students who can find slope but cannot finish the equation of the line, often stopping after the slope. Present levels on slope from two points (ma-alg-026) show readiness.
- Baseline
- Score each equation as correct only when both slope and intercept are right; record partial progress. Intercept errors usually come from sign mistakes.
- Tips
- Real data (two prices over time) link this to prediction. Point-slope form is an option for students who find it easier.
- Limits
- Six items per probe. Non-integer slopes are not included unless written into the condition.

Goal
By the annual IEP review date, given 6 pairs of points with integer coordinates, the student will find the slope, find the y-intercept using one point, and write the equation in slope-intercept form independently with at least 67% accuracy on line equations from two points, in 3 of 4 consecutive biweekly probes, as measured by work-sample analysis collected every two weeks.
Baseline: 17% accuracy.

Met: Method produces the metric. Work-sample analysis gives percent accuracy data.
Met: Review timeframe. Stated.
Met: Baseline and target compatible. Same unit, change in the right direction.
Met: Aligned with area of need. Still about Algebra & Equations.
Met: Level of support. Defined.
Met: Blanks filled in. Nothing left to fill in.
Checks structure and wording only. Whether the goal fits the student is the team's call.
Short-term objectives (optional)
When are objectives required?Required for students on alternate assessments (34 CFR §300.320(a)(2)(ii)); some states require them for everyone.

- Score only items the student attempted unless the goal defines a fixed set of items. Use the same denominator every session.
- Percent = numerator ÷ denominator × 100. Round to one decimal place.
- Record the support actually provided, even if the goal is independent performance.
