Question

the formula for converting Celsius temperatures to Fahrenheit temperatures is a linear equation. water freezes at 0 degree Celsius, or 32 degree Fahrenheit. find the slope and y-intercept for a graph that gives degrees Celsius on the horizontal axis and degrees Fahrenheit on the vertical axis. then write an equation in slope intercept form that converts degrees Celsius into degrees Fahrenheit.

Answer 1

Let x be temperature in Celsius and y in Fahrenheit.

when x=0, y=32
the y intercept is the point where x =0 so the intercept is on y=32.

the slope is 1.8

the slope intercept is in a form of y=mx+b where m is the slope and b is the intercept.

the answer is y =1.8x+32
