Answer:
y =-0.3x + 105
Explanation:
x1-x2/y1- y2 is the method to use to find the answer, so it
= (94.5-97.5) / (35-25) which
= (-3) / (10) which =-0.3.
That is m for ya, and for b,
Sub the first point (25, 97.5) into the equation of this line:
97.5 = (-0.3)*(25) + b => b = 97.5 - (-7.5) = 105
In conclusion, the equation is y =-0.3x + 105

Answer:

y = -0.3x + 105

Explanation:

x1 - x2 / y1 - y2 is the method to use to find the answer, so it

= (94.5-97.5) / (35-25) which

= (-3) / (10) which = -0.3.

That is m for ya, and for b,

Sub the first point (25, 97.5) into the equation of this line:

97.5 = (-0.3)*(25) + b => b = 97.5 - (-7.5) = 105

In conclusion, the equation is y = -0.3x + 105.
