Two or more equations that contain two or more variables is called what

How do you spell explosion

(The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r. The number r is called the constant of the equation ax + by = r. Examples. 10x - 3y = 5 and -2x - 4y = 7 are linear equations in two variables.

Step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
