Answer:
the first one
Step-by-step explanation:
Answer:
y=770-55x --- given
y - 770 = 770 - 55x - 770 ----subtraction property of equality
y = -55x + 770 ---Simplification
y-770/-55 = -55x/-55 --- Division property of equality
-y-770/55=x---Simplification
Step-by-step explanation:
Answer: They show numerical value. You have to make them clear.
Step-by-step explanation:
The answers is 3/9 which you can check by reducing. It reduces to 1/3. Basically you go 1/3 = x/9 then cross multiple to get 9=3x do the division so 3x/3 and 9/3 and you get 3/9.
Answer: y-6 = 0.5 (x-8)
Step-by-step explanation:
y − y1 = m(x − x1)
The equation is useful when we know:
one point on the line: (x1,y1)
and the slope of the line: m,
and want to find other points on the line.
Have a play with it first (move the point, try different slopes):
