Answer: 1 year
Step-by-step explanation:
1. Make an equation for both Types in standard y = mx + b form, with “b” being how tall the tree already is (so b for Type A will be 9, and b for Type B will be 2). Let “m” be equal to how many inches each tree grows per year (m for Type A will be 17, m for Type B will be 24)
2. Now you have the equations!
Type A: y = 17x+9
Type B: y = 24x+2
3. The problem is asking for how many years (represented by “x”) it will take for the trees to be of equal height, so set both of the equations equal to each other
17x+9 = 24x+2
4. Solve! (picture attached)
I hope this helped! feel free to comment if you need any clarification, though!

Answer:
Step-by-step explanation:
Given: Emelina wrote the equation of a line in point-slope form as shown below.
To write the equation in intercept form, first we multiply 3 inside the bracket values in the right side , we get
Now, subtract 4 from both sides , we get
Hence, Emelina’s equation in slope-intercept form :
Answer:
2y = x + 2
Step-by-step explanation:
Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;
From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:
Joining the points gives a straight line, which means a constant gradient of ¹/₂
Use the line equation formula to get the function:
y - y₁ = m(x - x₁)
m = ¹/₂
x₁ = 0
y₁ = 1
y - 1 = ¹/₂.(x - 0)
y - 1 = ¹/₂.x
2y - 2 = x
2y = x + 2
