Find the equation of the line with a given gradient through a given point by substituting the point into y = mx + c to find c; include negative and fractional gradients and points with negative coordinates. The two-point version is the sibling; perpendicular gradients are Higher. Both tiers. (A9)

• Fluency — direct questions on the line through a point with a given gradient, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
