What number produces an irrational number when multiplied by -1.25

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.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
