What would be the y-coordinates of the first two points on a graph of the additive rule x+25?(1 point)
(1,?), (2,?)
The additive rule x + 25 is an equation that adds 25 to any value of x.
To find the y-coordinates for the given x-values (1 and 2), substitute them into the equation:
For x = 1:
y = 1 + 25
y = 26
So, the y-coordinate for the point (1, ?) is 26.
For x = 2:
y = 2 + 25
y = 27
So, the y-coordinate for the point (2, ?) is 27.
A graph of an additive pattern contains the points (3,16) and (8,21) . What expression does the graph represent?(1 point)
x+?
To find the expression represented by the graph of an additive pattern containing the points (3, 16) and (8, 21), we need to calculate the change in the y-coordinate (Δy) when the x-coordinate changes by 5 (from 3 to 8).
Δy = 21 - 16
Δy = 5
Now, we can form the expression based on the change in the y-coordinate and the change in the x-coordinate:
Expression: x + 5
So, the expression represented by the graph is x + 5.
that's wrong
Apologies for the mistake in the previous response. Let's correct that.
To find the expression represented by the graph of an additive pattern containing the points (3, 16) and (8, 21), we can calculate the difference in the y-coordinates (which tells us how much the y-value changes when the x-value increases by 5).
From (3, 16) to (8, 21), the y-coordinate changes by 21 - 16 = 5 when the x-coordinate changes by 8 - 3 = 5.
Therefore, the expression that represents this additive pattern is x + 5.
So, the correct expression represented by the graph is x + 5.
