Question 1007452
At 109°F, a certain insect chirps at a rate of 98 times per minute, and at 112°F, they chirp 122 times per minute.
 Write an equation in slope-intercept form that represents the situation.
:
Assign the given values as follows
x1=109; y1=98
x2=112; y2=122
Slope formula m = {{{((y2-y1))/((x2-x1))}}}
m = {{{((122-98))/((112-109))}}} = {{{24/3}}} = 8 is the slope
:
Find the equation using the point/slope form y - y1 = m(x - x1)
y - 98 = 8(x - 109)
y - 98 = 8x - 872
y = 8x - 872 + 98
y = 8x - 774 is the equation

you can check this for yourself, see if the given values for x yield the value for y
