your equation y=3x-5 is a line. this line crosses the y-axis at -5 and the x-axis at 5/3. the slope is 3/1
12 (x is -3)
algebra
5 times y is the same as 5y in algebra
it is a straight line equation with a slope of 1 and a y intercept of -4
If: 6y-8 = 10 Then: y = 3
(the shape is an upside down 'u').
In algebra, (3y) represents a term where the variable (y) is multiplied by the coefficient 3. It indicates three times the value of (y). For example, if (y) equals 2, then (3y) would equal 6. This expression is commonly used in equations and functions to represent relationships involving the variable (y).
Add the two equations together, notice that the y and -y cancel. You can solve for x. Take your value of x and put it into either equation. Solve for y. Done. Also, don't mark this question as calculus. This is algebra.
This is the equation of a straight line. It can be rearranged as {y = (1/3)*x - 23/3}
If your shape is a rectangle then your y=30cm
In algebra we consider x,y and z are variables.
The x in y=mx+b is the independent variable. You could solve for x, making this a function of y, with simple algebra. y = mx + b y - b = mx (y-b)/m = x
