Question

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4?

y-1= 4 (x-3)
y=1=4 (x+3)
y-3= 4 (x-1)
y+3=4 (x+1)
My sister needs help on this so can anyone be quick to answer IF you know the answer. Thank you luvs! :)

Answer 1

`\displaystyle y + 3 = 4(x + 1)`

Explanation:

In the Point-Slope Formula [y - y₁ = m(x - x₁)], all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.
