Question

What is the equation in point-slope form of the line passing through (-2, 1) and (4, 13)? (1 points)
Question 15 options:
1) y - 1 = -2(x - 4)
2) y - 1 = 2(x + 2)
3) y - 13 = -2(x + 2)
4) y - 13 = 2(x + 4)

Answer 1

2)

Answer 2

\[m=\frac{y-y_1}{x-x_1}\]

so

\[(x-x_1)m=y-y_1\]

so what is m?

\[m=\frac{13-1}{4-(-2)}=\frac{12}{6}=2\]

y-1=2(x-(-2))
y-1=2(x+2)
