Answer:
y = -7x + 10
Step-by-step explanation:
Using a point slope form equation
y - y1 = m( x - x1)
Given
Point = ( 1 , 3)
Slope = -7
Insert the values into
y - y1 = m(x - x1)
x1 = 1
y1 = 3
y - 3 = m( x - 1)
m = -7
y - 3 = -7(x - 1)
Using a slope intercept form equation
y = mx + c
Open the bracket
y - 3 = -7x + 7
y = -7x + 7 + 3
y = -7x + 10
The equation of the line is
y = -7x + 10
