What equation is graphed in this figure?
y−4=−13(x+2)
y−3=13(x+1)
y+2=−3(x−1)
y−5=3(x−1)

Answer:
y + 2 = -3(x - 1) Option C
Explanation :
In given graph y intercept is (0,1)
So, we check all the equations whose y intercept is (0,1)
We know the slope intercept form of line
y = mx + b
where b is y intercept
We write every equation in slope intercept form
Start from equation (1)
y - 4 = -13(x+2)
y - 4 = -13x - 26
y = -13x -22
y intercept is -22
Second equation:
y - 3 = 13x + 13
y = 13x + 16 y intercept is 16
Third equation:
y + 2 = -3x + 3
y = -3x + 1
y intercept is 1
So this is correct answer.
