Question

The point where the graphs of two equations intersect has y-coordinate 2. One equation is y="-" 3x+5. Find the other equation if its graph has a slope of 1.

Answer 1

The equation of the line is y= x + 2

Explanation:

Answer 2

y = -3x + 5

Let y = 2

2 = -3x +5

-3 = -3x

x = 1

(1, 2)

y = mx + b

y = 1x + b

2 = 1 + b

b = 1

y = x + 1
