Question

13) through: (1, 2), slope = 7

A) y = -5x+4 B) y = -5x+7
C) y = 4x - 5 D) y = 7x - 5
​

Answer 1

D

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

Answer 2

Answer: D

Explanation:

if the slope is 7, mx + b =y the slope is m. that’s the only one that makes sense. hope this helps!
