B)57 is the answer for your question
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is

, so in this case, it is

, which comes to

. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=

x-

.
2. Use the same process as in question 1 to find:
y=-7x+11
Answer:
a) Graph are attached ,Red line shows the function y=3x-2 while blue line represents the function y=-5
b)(x,y)=(-1,-5)
Step-by-step explanation:
b)To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
c)Given that
y=-5
and y=3x-2
compare the right hand side of the above two equation and solve for x
3x-2=-5
or 3x=-3
or x=-1
so the solution to the given system of linear equations is =(-1,-5)
Answer:
36
Step-by-step explanation:
First you would solve what's in the parenthesis because the Order of Pemdas.
Second you would multiply the answer of what's in the parenthesis which is 3 to 12.
Third you would get the answer which is 36!
