(-2,-1) and (2,-6) A. find the slope of the line that passes through the given pt. B.find the standard form of the equation of the line C. find the slope intercept form of the equation of the line (I need solution) Answers: A. -5/4 B. 5x+4y=14 C. y=-5/4 x=-7/2
a. m= -6 - -1/2- -2 = -5/4 i need b and c solutions
i got the wrong answer

(-2,-1) and (2,-6) Find the Slope: Y2-Y1/ X2-X1 m= -6-(-1)=-5 2-(-2)= 4 m=-5/4 To find the standard form of the equation of the line and the slope intercept, we use the formula Y-Y1= m(X-X1). You can you choose any of the ordered pairs given, but just use one. Im going to use (2, -6) and substitute into the formula. Y-(-6)=-5/4(X-2) Y+6= -5/4x+5/2 -6 -6 ________________________ y= -5/4x-7/2 Now just put this in Ax+By=C and you have your answer!!
