Ex 10.3, 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 โˆ’ x 7y = โˆ’ x y = ( โˆ’ ๐‘ฅ)/7 y = ( โˆ’ ๐‘ฅ)/7 + 0 y = โˆ’ 1/7x + 0 This equation is of the form y = mx + c where m = โˆ’ 1/7 & c = 0 Hence Slope = m = ( โˆ’ 1)/7 y intercept = c = 0 Ex 10.3, 1 Reduce the following equations into slope-intercept form and find their slopes and the y-intercepts. (ii) 6x + 3y โ€“ 5 = 0 6x + 3y โ€“ 5 = 0 3y = โ€“ 6x + 5 y = (โˆ’6๐‘ฅ + 5)/3 y = (โˆ’6๐‘ฅ)/3 + 5/3 y = โ€“ 2x + 5/3 This equation is of the form y = mx + c where m = โ€“2 & c = 5/3 Hence, slope m = โ€“2 & y intercept = 5/3 Ex 10.3, 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
