Ex10.3, 1 Reduce the following equations into slope-intercept form and find their slopes and the y-intercepts. x + 7y = 0 x + 7y = 0 7y = 0 − x 7y = − x y = ( − 𝑥)/7 y = ( − 𝑥)/7 + 0 y = − 1/7x + 0 This equation is of the form y = mx + c where m = − 1/7 & c = 0 Hence Slope = m = ( − 1)/7 y intercept = c = 0 Ex10.3, 1 Reduce the following equations into slope-intercept form and find their slopes and the y-intercepts. (ii) 6x + 3y – 5 = 0 6x + 3y – 5 = 0 3y = 6x + 5 y = (6𝑥 + 5)/3 y = 6𝑥/3 + 5/3 y = 2x + 5/3 This equation is of the form y = mx + c where m = 2 & c = 5/3 Hence, slope m = 2 & y intercept = 5/3 Ex10.3, 1 Reduce the following equations into slope-intercept form and find their slopes and the y-intercepts. (iii) y = 0 y = 0 This can be written as y = 0 + 0 y = 0x + 0 This equation is of the form y = mx + c where m = 0 & c = 0 Hence slope = m = 0 & y-intercept = 0
