Which form is most useful for graphing a line if you know the x-intercept and y-intercept?

A

Standard Form (Ax+By=CAx + By = C)

B

Slope-Intercept Form (y=mx+by = mx + b)

C

Point-Slope Form (y−y1=m(x−x1)y - y_1 = m(x - x_1))

D

Direct Variation (y=kxy = kx)

Correct Answer: A

Choice A is the correct answer. Intercept method.

  1. Standard Form: Easy to find intercepts by covering up terms (Ax=C,By=CAx=C, By=C).
  2. Graphing: Plotting two intercepts is a very fast way to graph.

💡 Strategic Tip: Slope-intercept is best for graphing with slope. Standard is best for intercepts.

Choice B is incorrect because it only gives the y-intercept directly. Choice C is incorrect because it requires calculation for intercepts. Choice D is incorrect because it only works for lines through the origin.
