Answer:
y = 8x - 55
Step-by-step explanation:
Given
Point (x1,y1) = (7,1)
Slope, m = 8
Required
Determine the equation of the line
The question asks that the equation to be in form: y = mx + b
This above form is a representation of point-slope and is calculated using the following formula:
y - y1 = m(x - x1)
Substitute values for y1, x1 and m
y - 1 = 8(x - 7)
Open bracket
y - 1 = 8x - 56
Collect Like Terms
y = 8x - 56 + 1
y = 8x - 55
Hence, the calculated line equation in form of y = mx + b is y = 8x - 55
