Write the equation of a line in point slope form that has a slope of − 3/4 and passes through the point (4, 5). Please explain h
ow you got the answer and what formulas you used.
1 answer:
I guess by slope, you mean gradient.
By knowing the gradient, and a coordinate at which the line passes through, we can use:
y - y1 = m(x - x1)
to get the equation of the line in the form (y = mx + c).
y - 5 = (-3 / 4)(x - 4)
y - 5 = (-3 / 4)x + 3
Rearrange.
y = (-3 / 4)x + 8
