Can someone help me with this one i don't know how to write out the equation it's asking for

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 zeros of each function. f(x) = 6x^2 - 7x - 20

In a column proof the right column states your reasons
