Answer: correct
Answer:
y=-6
Step-by-step explanation:
Method 1:
Both the y coordinates of the points are the same and the x coordinates are distinct.
Therefore the straight line passing through the point is parallel to X-axis.
The common y coordinate is -6, therefore the line equation is y=-6.
Method 2:
We will solve it using general line equation
(y-y1)=(
)(x-x1)
where (x1,y1) and (x2,y2) are the 2 points.
- (y+6)=(
)(x+2)
Answer: 1- function 1 has the greater rate of change but function 2 has the greater y-intercept
Step-by-step explanation:
We know that function 1 is:
y = f₁(x) = 0.75*x - 1
And for the second linear equation we can see that it passes through the points (-3, -1) and (0,1)
Then the slope is:
a = (1 - (-1))/(0 - (-3)) = 2/3
then the equation is something like:
y = f₂(x) = (2/3)*x + b
To find the value of b, we use the fact that when x = 0, we have y = 1.
Then:
1 = (2/3)*0 + b
1 = b
Then the equation for function 2 is:
f₂(x) = (2/3)*x + 1
So the two equations are:
f₁(x) = 0.75*x - 1
f₂(x) = (2/3)*x + 1
Where we can see that function 1 has a greater slope (rate of change) and function two has a greater y-intercept.
Then the correct option is
(1- function 1 has the greater rate of change but function 2 has the greater y-intercept)
