Can some one me, i’ve been asking for so long

Write an equation in standard form of the line that passes through the point and has the given slope. ( -2, 4) ; m = -6which of the following best describes the technique used to graph the equation using the slope and y-intercept? y = 5x + 10write the standard form of the equation of the line through the given point with the given slope. point , 4); slope -3/2

Aquadratic equation in standard from is written ax^2= bx+c, where a, b and c are real numbers and a is not zero?
