V^2+3v-5=0
round to nearest hundredth

V² + 3v - 5 = 0
v = -(3) ± √((3)² - 4(1)(-5))
                    2(1)
v = -3 ± √(9 + 20)
                2
v = -3 ± √(29)
            2
v = -3 ± 5.38
            2
v = -1.5 ± 2.69
v = -1.5 + 2.69    or    v = -1.5 - 2.69
v = 1.19    or    v = -3.19

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
