To find the equation of a line given a specific slope and a point, we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)
In this formula:
m
is the slope of the line.(x1, y1)
is a point on the line.
We are given a slope m = 7
and a point (x1, y1) = (3, 4)
.
Substituting the given values into the point-slope formula:
y - 4 = 7(x - 3)
Now, let’s simplify this equation:
- Distribute
7
on the right side: - Add
4
to both sides to isolatey
:
y - 4 = 7x - 21
y = 7x - 21 + 4
y = 7x - 17
So, the equation of the line with a slope of 7
that passes through the point (3, 4)
is:
y = 7x - 17
