Answer:
6x + y = 19
Explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 3; y₁ = 1; m = -6 Substitute the values
y – 1 = -6(x-3) Remove parentheses
y – 1 = -6x + 18 Add 1 to each side
y = -6x + 19 Add 6x to each side
6x + y = 19
The graph is a straight line with a y-intercept at y = 19 and
slope = -18/3 = -6.
bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
then we'd end up with 6x + y = 19.
