Question

Anyone know the answer to this?

Answer 1

Answer: y = 3x+5, 3, (-1,2)

Explanation:

y = mx + c where m is the slope, so we must find the slope

Slope = rise/run = (5-2)/(0-(-1)) = 3

So y = 3x + c

To find c, we have to substitute one of the coordinates on the graph into the equation, (-1,2), the point that is marked

2 = 3(-1) + c

c = 5

So the equation of the graph is y = 3x + 5

Answer 2

Slope = 3/1 =3
Point = (-1, 2)
Point slope form = y - y_1 = m (x - x_1)
Equation = y - 2 = 3 (x + 1)
