Grade 11 Math Worksheet - Challenge Me

NameDate

Circle the best answer, or write your answer on the line.

  1. Jun slides the line y = 2x + c until it touches y = x² − 6x + 10 at exactly one point. What is c?

  2. Milo slides the line y = 4x + c until it touches y = x² − 2x + 7 at exactly one point. What is c?

  3. Noah slides the line y = 4x + c until it touches y = x² + 8x + 20 at exactly one point. What is c?

  4. On a grid, Ren draws a tossed ball's path, y = -x² + 9x, and a ramp, y = 2x + 10. How high is the higher of the two crossing points?

  5. On a grid, Zee draws a jump ramp's curve, y = -x² + 4x, and a slide, y = -x + 4. How high is the higher of the two crossing points?

  6. On a grid, Esme draws a rainbow arch, y = -x² + 5x, and a slide, y = -x + 5. How high is the higher of the two crossing points?

  7. Jun solves x² + y² = 13 and y = x² − 1 by putting x² = y + 1 into the circle. How many points do they share?

    • No points
    • Two points
    • Four points
    • One point
  8. Luz solves x² + y² = 29 and y = x² + 1 by putting x² = y − 1 into the circle. How many points do they share?

    • One point
    • No points
    • Four points
    • Two points
  9. Milo solves x² + y² = 25 and y = x² − 5 by putting x² = y + 5 into the circle. How many points do they share?

    • Two points
    • Three points
    • Four points, with a touch counted twice
    • No points
  10. Noah solves x² + y² = 16 and y = x² − 4 by putting x² = y + 4 into the circle. How many points do they share?

    • Three points
    • No points
    • Four points
    • Two points

About this worksheet

Systems with a quadratic: a line and a parabola, a line and a circle, two parabolas. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can check whether a point solves a system.
  • I can find every point where a line meets a parabola or a circle.
  • I can tell from the discriminant whether they meet twice, once or not at all.

Standard: A-REI.C.7

Words to know

system: Two equations that must both be true at once.

substitute: Put one rule in place of y in the other.

meeting point: A point on both graphs: a row where the outputs match.

touch: Meet at exactly one point, with discriminant 0.

Common mistakes

Your child checked the point in one equation only.

Your child made the square of a negative number negative.

Your child doubled x instead of squaring it.

What to say

Ask: does the point fit the other equation too?

Ask: what is (-3) × (-3)?

Ask: is 3² the same as 2 × 3?

Questions parents ask

What is the most common mistake with systems with a quadratic: a line and a parabola, a line and a circle, two parabolas?
