Answer:
line 1 and 2 I think sorry if I'm wrong
Y=3x+5
Gradient=3
y-y1=m(x-x1)
If the points are (7,1)
y-1=3(x-7)
y-1=3x-21
y=3x-20 as your equation
Note: when lines are parallel they have equal gradient
Answer:
68
Step-by-step explanation:
First, we can try to set x as big as possible. To do that, we realize that x<=5, so the biggest value possible of x is 5.
Now, we want to set y as big as possible. To do that, we need to use the fourth equation 4x-y>=1. Since x is 5, the greatest possible value of y is 19.
After checking that x and y fit the constraints, we can plug these 2 numbers in to solve for the biggest value of c;
c=6*5+2*19=30+38=68
