Answer:
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
The slope of the line is 7 and it passes through (8,6).
To determine the intercept, we would substitute x = 8, y = 6 and m= 7 into y = mx + c. It becomes
6 = 7 × 8 + c
c = 6 - 56 = - 50
The equation becomes
y = 7x - 50
