Which is an equation, in point-slope form, of a line that passes through the points (2,9) and (4,5)?

select each correct answer.

y−9=−12(x−2)

y−9=−2(x−2)

y−5=−2(x−4)

y−4=−2(x−5)

y−5=−12(x−4)

y−2=−2(x−9)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
