Question

Write the equation of the line in slope intercept form and standard form.

Answer 1

Slope-intercept: y = -3x + 3

Standard: 3x + y = 3

Explanation:

Given (0,3) and (1,0)

Slope m = (y2-y1)/(x2-x1)

m = (0 - 3)/(1 - 0)

m = -3/1 = -3

Slope-intercept: y = mx + b

using (1,0)

0 = -3(1) + b

0 = -3 + b

b = 3

so y = -3x + 3

Slope-intercept: y = -3x + 3

Standard: 3x + y = 3
