Question

FIND THE EQUATION OF THE LINE . USE EXACT NUMBERS

Answer 1

• (1,4)
• (0,7)

Slope

• m=7-4/-1
• m=3/-1
• m=-3

Equation

• y-y1=m(x-x1)
• y-4=-3(x-1)
• y-4=-3x+3
• y=-3x+7

Answer 2

• y = -3x + 7

Explanation:

Use points on the graph:

• (0, 7) and (2, 1)

Find the slope:

• m = (1 - 7)/ 2 = -3

The y-intercept is known b = 7, so the equation is:

• y = mx + b
• y = -3x + 7
