I don't understand
Hey. The answer to each is actually using the equation of the line which is y = mx + c where m is the gradient and c is the y intercept. Since for each part they have given you two coordinates, you can find the gradient (m) which is as follows:
m=(y2-y1)/(x2-x1)
Once you get the m value, use any one of the two points given to find your y-intercept which is your c value.
Hope you understand. Otherwise i can re-do it
m=(y2-y1)/(x2-x1)
Once you get the m value, use any one of the two points given to find your y-intercept which is your c value.
Hope you understand. Otherwise i can re-do it
Hey I understand now
