His Find an equation of the line that contains the given point and is perpendicular to the given line. Use a graphing calculator to verify the result.
(7,6), y = - 4x - 7
The equation of the line is
(Simplify your answer. Use integers or fractions for any numbers in the equation. Do not factor.)

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
