Answer:
Here,
slope (m)=-2
y- intercept (c)=-7
Now,
The equation of the line;
or,y=mx+c
or,y= -2x-7
or,2x+y+7=0 is the required equation....
Answer:
0.083
Step-by-step explanation:
Numbers of Cube = 6
Faces on coins = 2
Therefore, The total outcomes = 
Now the favourable outcome that he rolls a 4 & flips a head = 1
The probability that he rolls a 4 & flips a head = 1

=> The probability that he rolls a 4 & flips a head = 
Therefore, The probability that he rolls a 4 & flips a head = 0.083
Answer:
2. 9, 8+9
3. 17-8=9, 17, 8, 9
4. 13-7=6
Step-by-step explanation:
Congruent means Same Side, Same Shape.
If two angles are congruent, they are to be of the same size and same shape or a fraction of it (Dilation)
The unit rate is a ratio of change in y and into the change on x. It can also be the rise to run or the slope.
