Help your students prepare for their Maths GCSE with this free y=mx+c worksheet of 30+ questions and answers
y=mx+c is the general equation of a straight line. When written in the form y=mx+c, m is the gradient of the line and c is the y intercept. The gradient of a straight line tells us how steep the line is and the bigger the gradient, the steeper the line. A line with a negative gradient slopes downwards. The y intercept of the line tells us the y coordinate of the point where the line passes through the y axis.
Sometimes the equations of linear graphs may be written in a form other than y=mx+c. If this is the case, we can rearrange the equation into the form y=mx+c, i.e. make y the subject, to give us the gradient and y intercept of the line.
If we have a straight line graph, we can find the equation of the straight line by finding the gradient and the y intercept of the line and substituting these values into the equation y=mx+c. To find the gradient, we need to identify the x coordinates and y coordinates of two points, subtract the y values, subtract x values and then divide them.
Looking forward, students can then progress to additional straight line graphs worksheets and on to more algebra worksheets, for example a simplifying expressions worksheet or simultaneous equations worksheet.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
