A linear equation is similar to a linear graph in that key data from the equation is clearly visible on the graph. A linear equation of y = 4x + 5 shows us that the y-intercept (or "b") is +5. This is where our line crosses the y-axis, and provides us with the information that the point (0, 5) exists on our line, making it the easiest point to draw on our graph every time! The equation also shows us that there is a slope (or "m") of 4. This means we must do the long-form of slope, which is "rise over run" or "change in y, divided by change in x". A slope of 4 is written as 4/1, or "four over one", showing we 'rise' 4 units on our graph, and 'run' 1 unit...clearly showing a slope of 4.
If: 5x+7y+29 = 0 and 11x-3y-65 = 0 Then: 5x+7y = -29 and 11x-3y = 65 Multiply all terms in the 1st equation by 11 and all terms in the 2nd equation by 5 So: 55x+77y = -319 and 55x-15y = 325 Subtract the 1st equation from the 2nd equation: 92y = -644 => y = -7 Therefore by substitution the point of contact is at: (4, -7)
Great !There are an infinite number of pairs of numbers that (x,y) can be.You can make a neat graph showing their relationship, and ... when you pick a number for 'x' or 'y' ...showing you what the other one has to be.On x-y graph coordinates, this equation is a straight line. It crosses the y-axis at the point [ y = 3 ],and has a slope of [ -1 ] ... meaning that for every inch that 'x' increases, the line drops 1 inch lower.
A proportion.

A balanced equation is representative for the amounts and nature for reactants and products involved.

its like a bar graph but with little crosses and you join them up with lines
Acids and alkali mixing
limestone + lemon lol
An equation showing all dissolved compounds as ions
The chemical equation showing the reaction of ammonia and water is: NH3 + H2O -> NH4+ + OH-. This reaction results in the formation of ammonium ion (NH4+) and hydroxide ion (OH-).
