What is the equation of a line with a slope of negative 2 that passes through the point open paren 6 comma 8 close paren ?

Use the point-slope equation with slope −2 through (6, 8): y − 8 = −2(x − 6). Simplifying gives y − 8 = −2x + 12, so 2x + y = 20. Therefore, the equation is “2x plus y is equal to 20.”
