Here's a graph of a linear function. write the equation that describes that function.

Step-by-step explanation:

To find the equation of a linear function , we pick two points from the graph

LEts pick two points (0,-4) and (4,-3)

Equation of linear function is

where m is the slope and b is the y intercept

(0,-4) is (x1,y1) and (4,-3) is (x2,y2)

y intercept is the point where the graph crosses y axis

y intercept

Linear function becomes

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
