Answer:
y= -9x+14
Step-by-step explanation:
the equation of a straight line is y=mx+c
m is the slope
And we are given a y and x term
So we substitute these into the equation:
5= -9(1) + c
rearragne to find c
14= c
so the full equation is:
y= -9x+14

Answer:
w = 8
Step-by-step explanation:
4+ 1/4 w=6
Subtract 4 from each side
4-4+ 1/4 w=6-4
1/4w = 2
Multiply each side by 4
4* 1/4 w=2*4
w = 8
The answer is 9
One square is equal to one. for the rest just substitute the x and y for the given values
