3. What is the equation in slope-intercept form of
the line that passes through (3,4) and is
perpendicular to y=-x+ 2?
A) y=-x-1
B) y=x+1
C) y=zx-1
D) y=-x+1

Respuesta :

Answer:

Step-by-step explanation:

y = -x + 2....the slope here is -1. A perpendicular line will have a negative reciprocal slope. So the slope we need is 1.

y = mx + b

slope(m) = 1

(3,4)....x = 3 and y = 4

now we sub and find b, the y int

4 = 3(1) + b

4 = 3 + b

4 - 3 = b

1 = b

so ur equation is : y = x + 1 <===
