The typical form of the slope intercept equation would be:
Y = mX + B
Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).
---------------------------------------
Slope :
---------------------------------------
y = -5x + 2
Slope = -5
---------------------------------------
y - intercept :
---------------------------------------
At (0. 3), y-intercept = 3
---------------------------------------
Equation :
---------------------------------------
y = mx + b
y = -5x + 3
---------------------------------------
Answer : y = -5 + 3
---------------------------------------
I think you could try adding up all the x and then divided
C because i just took de test
