Question

Please help what is the following (-3 6); m= 1/2

Answer 1

Y - y1 = m(x - x1)

y - 6 = (1/2)(x - (-3))

y - 6 = (1/2)(x + 3)

Answer 2

What do you need? I assume you need to write an equation if so then
y - 6 = 1/2(x +3)
y - 6 = 1/2(x) + 3/2
y = 1/2(x) + 15/2

equation in sloep intercept form:
y = 1/2(x) + 15/2

hope it helps
