Use the discriminant to describe the roots of each equation. Then select the best description. 7x2 + 1 = 5x double root real and irrational root real and rational root imaginary root

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

Can some one me with these questions
