Answer:
a. y= 0.613x - 4.141
Step-by-step explanation:
y= ~ -4 when x= 0 so that will be our y-intercept.
so our option would be either A or D
if you look closely, the x goes up when y goes up, which means the slope is a positive
Answer:
9/10
Step-by-step explanation:
To find out if it's a linear equation, you would solve it so that it becomes the
y=mx+b formula.
So, you would subtract 2x from both side than divide it by 4.
It would then look like y=-1/2x+4. This shows that since 2x+4y=16 can be put into the y=mx+b formula, it is a linear equation.
So, the answer is yes.
Answer: y=-.667x+1
Step-by-step explanation:
1. Firstly, substitute the coordinates of the two points into the slope intercept equation:
(1) y₁ = mx₁ + b
(2) y₂ = mx₂ + b
2. Then, subtract the first equation from the second:
y₂ - y₁ = m(x₂ - x₁)
3. Finally, divide both sides of the equation by (x₂ - x₁) to find the slope:
m = (y₂ - y₁)/(x₂ - x₁)
4. Once you have found the slope, you can substitute it into the first or second equation to find the y-intercept:
y₁ = x₁(y₂ - y₁)/(x₂ - x₁) + b
b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
