Which Line Passes Through The Points (3,4) And (8,1), Write It In Slope-Intercept Form
Which line passes through the points (3,4) and (8,1), write it in slope-intercept form
Answer:
y = -3x/5 + 29/5 ⇒ slope-intercept form
3x + 5y = 29 ⇒ Standard form
3x + 5y - 29 = 0 ⇒ General form
Step-by-step explanation:
Slope-intercept form:
y = mx +
Given two points:
(x₁, y₁) = (3,4)
(x₂, y₂) = (8,1)
Use the two-point form to find the equation y=mx+b:
y - y₁ = (y₂-y₁)/(x₂-x₁) (x - x₁)
y - 4 = (1-4)/8-3)(x - 3)
y - 4 = (-3/5)(x - 3)
y = -3x/5 + 9/5 + 4
y = -3x/5 + (9/5) + 20/5
y = -3x/5 + 29/5 ⇒ slope-intercept form y=mx+
Where:
Slope (m) = -3/5
y-intercept (b) = 29/5
Standard form and General forms:
y = -3x/5 + 29/5
(5)(y = -3x/5 + 29/5)(5)
5y = -3x + 29
3x + 5y = 29 ⇒ Standard form
3x + 5y - 29 = 0 ⇒ General form
