Best ResponseYou've already chosen the best response.1The equation of a straight line is \[y=mx+c\] where m is the slope and c is the yintercept. To find the slope divide the difference in y values, by the difference in x values thus \[m=\frac{y_1y_2}{x_1x_2}\]. Once you have found the slope, choose a point, and plug the values for x and y into the straight line equation and solve for c. So in this instance we would have a slope of \[m=\frac{63}{07}=3/7\]. So we now have \[y=\frac{3}{7}x+c\]. We choose the point (0,6) where x = 0 and y = 6, and plug the numbers in to get \[6=\frac{3}{7}\times0+c\] making c = 6. So the final equation is \[y=\frac{3}{7}x+6\] or to remove the fraction multiply everything by 7 and we get \[7y=3x+42\]
