13) through: (1, 2), slope = 7
a) y = -5x+4 b) y = -5x+7
c) y = 4x - 5 d) y = 7x - 5

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = 7, thus

y = 7x + c ← is the partial equation

To find c substitute (1, 2) into the partial equation

2 = 7 + c ⇒ c = 2 - 7 = - 5

y = 7x - 5 → D

i would need to see the dot plot : )
