Gradient (m) = change in y/change in x
-2-5/0–2 = 3.5
gradient (m) = 3.5
Now evaluate one of the coordinates and the gradient in the equation
y = mx + c
-2 = 3.5(0) + c
c = -2
so the answer is
y = 3.5x -2
Start with your given equation - F=9/5C+32
Subtract 32 from both sides - F-32=(9/5) degrees C
Multiply both sides by 5 - 5(F-32)=9C
Divide both sides by 9 to isolate C - (5/9)(F-32)=C
Answer - C=(5/9)(F-32)

Answer:
h(9)=62
Step-by-step explanation:
h(x)=8x-10
62=8x-10 <em>(</em><em>+</em><em>1</em><em>0</em><em>)</em>
72=8x <em>(</em><em>÷</em><em>8</em><em>)</em>
9=x
Answer:
x=2 y=8 ---> (2;8)
Step-by-step explanation:
2x+5y=44
6x-4=y
1.
2x+5(6x-4)=44
2x+30x-20=44
32x=64
x=2
2.
6x-4=y
6*2-4=y
12-4=y
y=8
