What is the equation for the line that passes through the point (9,6) and has a slope of -1 y=1x+9
y=1x+15

y=-x+15

Step-by-step explanation:

hope this helps :)

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:
