y + 4 = - 7(x - 1)
y + 4 = - 7x + 7
y = - 7x + 7 - 4
y = - 7x + 3
Inform of: y = mx + c
Where, gradient m = - 7, and intercept c = 3
DONE !

y + 4= -7(x − 1) < == this is a line in point-slope form y − y₁ = m(x − x₁)
expand the brackets/parentheses
∴ y + 4= -7x + 7
subtract 4 from both sides
∴ y = -7x + 3 <== This is the same line in slope-intercept form y = mx + b
for completeness adding 7x to both side
∴ 7x + y = 3 <== This is the same line in standard form Ax + By = C [where A, B, C are all integers, and A is positive and in this form m = -A/B]

As you have NOT STATED ANY PROBLEM, no one else will, either !
y = - 7x + 3 is the equation of a line !
