Answer:
y = -5/2x - 4
Step-by-step explanation:
(0,-4) and (-4,6)
Slope:
m=(y2-y1)/(x2-x1)
m=(6+4)/(-4-0)
m=10/-4
m= -5/2
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = -5/2(x - 0)
y + 4 = -5/2x
y = -5/2x - 4
Answer:
- 39
Step-by-step explanation:
Step 1:

Answer:
1, (-5)(8)=-40 2, (4)(-4)=-16. 3, (-1)(-9)=9. 4 , (5)(6)=30. 5, (12)(-2)=-24. 6, (‐15)(9) =-135. 7. (5)(‐6)= -30. 8. 6(‐6) = -36. 9. (‐27)(14) = - 378. 10.(‐32)(0) = 0. 11.(128)(‐3)= -384. 12.(‐54)(‐4) = 216. 13.(+21) ÷ (+7)= +3
Step-by-step explanation:
positive number multiplied by positive number gives positive number
negative number (-ve) times positive number (+ve) gives -ve
-ve times -ve gives +ve
+ve times -ve gives -ve
