Directions: Use each graph below to write the equation of the line in slope-intercept form y=mx + b. Make sure to show your work.

Step-by-step explanation:

Y=mx+b

Slope (m) is rise over run.

1. rise= 4 run=5 therefore, slope=4/5

y=4/5x+b

b= y intercept

b= 4

Y=4/5x+4

2. rise= 1 run= 2 slope = -1/2

b= -1

Y= -1/2x - 1

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

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:
