The x-value at the point, denoted by d, is 18
<h3>Slope of a line </h3>
From the question, we are to determine the x-value at point B on the line
Given the points (x₁, y₁) and (x₂, y₂) on a line.
The slope, m, of a line with two points (x₁, y₁) and (x₂, y₂) on the line is given by the formula
m = (y₂ - y₁)/(x₂ - x₁)
From the given information,
Point A is (2, 1)
Point B is (d, 81)
That is,
x₁ = 2
y₁ = 1
x₂ = d
y₂ = 81
and
slope, m = 5
Thus,
5 = (81 - 1) / (d - 2)
5 = 80/(d -2)
5(d - 2) = 80
5d - 10 = 80
5d = 80 + 10
5d = 90
d = 90/5
d = 18
Hence, the x-value at the point, denoted by d, is 18

Elliot is 63 inch tall
Jackson is x inch tall
x + 9 = 63
x + 9 (-9) = 63 (-9)
x = 54
Jackson is 54 in. tall
hope this helps
Answer:
1,1
Step-by-step explanation:
have to do a graph then when you do the graph you find a point also to do a graph the number in front of the x in how much you go up over how many you go down and the random number like -1 is where you start on the y axis
