Answer:
x = 1.56 or x = -2.56
Step-by-step explanation:
From the equation;
x2 +x − 4 = 0
a = 1 , b = 1, and c = -4
x = (-b ± √(b² -4ac))/2a
= (-1 ± √(1²- 4×1×-4))/2
= ( -1 ± √(17)/2
= (-1 ± 4.12)/2
= (-1 + 4.12)/2 or (-1 - 4.12)/2
<u>x = 1.56 or x = -2.56</u>

Answer:
Slope = 2
Step-by-step explanation:
M = (y2 - y1)/(x2 - x1)
M = (-11 - -7)/(-6 - -4)
M = (-4)/(-2)
M = 2
