What is the equation of a line that passes throught the points (-4, 2) and (-8, -3)

y=5/4x+9/2

Step-by-step explanation:

Slope: 2+3/-4+8

=5/4

y-2=5/4(x+2)

y-2=5/4x+5/2 <because 5/4*2=10/4

y=5/4x+9/2

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

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:
