Write the slope-intercept form of the line eith a slope of 2 and a y-intercept of -4

y=2x-4

Step-by-step explanation:

slope=2=k

y-intercept in - 4 then n=-4

y=kx+n

y=2x-4

a) 7x=7

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:
