Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the graph
y2 = 5
y1 = 4
x2 = 4
x1 = 0
Slope, m = (5 - 4)/(4 - 0) = 1/4
To determine the intercept, c, we would substitute m = 1/4, x = 4 and y = 5 into y = mx + c. It becomes
5 = 1/4 × 4 + c
5 = 1 +c
c = 5 - 1 = 4
The equation becomes
y = x/4 + 4
