What are pointslope equations of the line going through -4 and -7 and 3 and 2?
Assuming the two points are (-4,-7) and (3,2) the equation for the slope would be (3-(-4))/(2-(-7)) which equals 7/9. If we use y=mx+b and the point (3,2) you get 2=(7/9)*3+b which simplifies to 2=2 1/3+b then by subtracting 2 1/3 from both sides you are left with b= -1/3. Thus the equation is y=7/9x-1/3.
Can you pass more than one line through two points?
Only one line can pass through two points, but this line can have different equations that could represent it. These are called dependent equations (because they represent the same line). * * * * * That is true for the Euclidean plane. But on surfaces that are not flat, there can be infinitely many lines through any pair of points.
What equations are helpful in GCSE further maths?
Quadratic, simultaneous and straight line equations
What is it called when a circle has lines going through it?
Rhumb line.
What is a inconsistent line?
its a system of equations, with no solution
What is linear equation in one variable?
Linear equations with one variable will either be horizontal or vertical lines. y=2 is a horizontal line going through (0,2)

What does an O with a line through it going diagnolly?
The line going through an "o" helps to clarify the letter o, from the number zero.
How do you write an equation for a line that passes through point and is parallel to the given line?
Both straight line equations will have the same slope or gradient but the y intercepts wll be different
What does a straight line going through a note mean?
line note
What is the equation of the line that passes through 1 5 and 4 11?
Plug both points into the equation of a line, y =m*x + b and then solve the system of equations for m and b to get equation of the line through the points.
How do you write an equation that is parallel to a given line and passes through the given point?
Parallel straight line equations have the same slope but with different y intercepts
How are linear equations and linear inequalities similar?
A linear equation corresponds to a line, and a linear inequality corresponds to a region bounded by a line. Consider the equation y = x-5. This could be graphed as a line going through (0,-5), (1,-4), (2,-3), and so on. The inequality y > x-5 would be the region above that line.

Quadratic, simultaneous and straight line equations
How can you prove that a line going through a circle is a line of symmetry?
The diameter of a circle is its line of symmetry and the lines can be infinite
What is it called when a circle has lines going through it?
Rhumb line.
