y = -11x - 7
y = -7x + 11
y = -7x - 11

Answer 1

hi
let's take the co-ordinates of the 2 points given in graph...
1st one - (-2,3)
2nd one - (-1 , -4)

now the slope of a function can be found by formula....\[slope = \frac{ Y _{2} - Y _{1} }{X _{2} -X _{1} }\]

here,
y2 = -4
y1 = 3
X2 = -1
x1 = -2

so....the slope can be written as....\[slope = \frac{ (-4) - 3 }{ (-1) -(2)}\]

wt is the slope then ???
