Well, when it comes to graphing an inequality, and you need to know whether the line is solid or dashed, look at the inequality sign..... (i do not remember that exact terms) anyway, if it is JUST > or < then it is dashed, that is because you are not including that number, just any number greater than or less than it...
however, if it is Greater than or Equal to
or
less than or equal to
where these two are including that # by having the "or equal to", it will be solid for it is INCLUDING what ever # we are using...
for example
y > 3 will be dashed
where as y is greater than or equal to 3 will be solid since the y could be 3
i cant really explain this well... but i hope i made it somewhat clear
Answer:
y= -x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Slope
Substitute m= -1 into the equation:
y= -1x +c
y= -x +c
To find the value of c, substitute a pair of coordinates.
When x= -7, y= 7,
7= -(-7) +c
7= 7 +c
c= 7 -7
c= 0
Thus, the equation of the line is y= -x.

Answer:the first one I think
Step-by-step explanation:I hope it’s right
Answer:
Q1: p = - 33
Q2: d = - 99
Q3: t = - 13
Step-by-step explanation:
Q1:
We solve this taking LCM.
We get:
Q4:
Again we proceed like Q1 by taking LCM.
We get:
Q7: 5t + 12 = 4t - 1
We club the like terms on either side.
Hence, the answer.
