A linear equation is y = mx + c where m is the gradient and c is the y-intercept. Linear equations are always graphically shown as a straight line, regardless of the gradient or the y-intercept.

-6

As for example in the straight line equation: y = 3x+5 the y intercept is 5 and the slope or gradient is 3

Y = ('x' times any number) + 7

You get a graph based on polar coordinates rather than Cartesian coordinates. Some shapes have simpler equations in polar coordinates: for example, a circle with centre at the origin and radius r, is simple R = r. A straight line through the origin and gradient (slope) m is tan(q) = m.

The y-intercept can be obtained from the straight line formula, y=mx+c. The y-intercept, c, is therefore given by c=-mx+y where m is the coefficient of gradient.

17x + 2y = 23 is the equation of a straight line with gradient -8.5 and intercept 11.5

Two coordinates are needed to determine the slope of a straight line equation.

y=mx+c where x and y are variables, m is the gradient (or slope) and c is the intercept on y (axis). that is the general equation of a straight line. if you had given some coordinates for the points one could extrapolate from that to find the full equation. since you have not, one cannot.

It would be a straight line with gradient 3, which would intercept the y axis at the point (0,2).

It was the Frenchman Rene Descartes who intoduced straight line equations in the form of y = mx+c whereas m is the slope and c is the y intercept

Straight line equations:- And if: 3x-4y = 8 Then: y = 0.75x-2 whereas 0.75 or 3/4 is the slope and -2 is the y intercept
