Graph the line that passes through the points (4,−9) and (−3,−2) and determine the equation of the line.

1

Step-by-step explanation:

-2-(-9)/-3-4

-2+9/-7

7/-7=1

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:
