Slope intercept form is y = mx + b, where m is the slope and b is the y intercept. To graph this, look at b. The number there is the y intercept. Look on the y axis on the graph and find the place where that number occurs. Plot that point, which will be (0, b). Then look at the m term. This is the slope. Imagine this number as a fraction. If it is a whole number, imagine it as the whole number divided by one. The fraction is the slope. The numerator is how far you move up or down, and the denomontator is how far you move left and right on the graph. Find the second point this way, then you can draw your line. Hope this helps!
y = 2x + 1.
A linear equation has the form of mx + b, while a quadratic equation's form is ax2+bx+c. Also, a linear equation's graph forms a line, while a quadratic equation's graph forms a parabola.
Normally a quadratic equation will graph out into a parabola. The standard form is f(x)=a(x-h)2+k
The slope of your quadratic equation in general form or standard form.
The graph of is shifted 3 units down and 2 units right. Which equation represents the new graph?
y = 2x + 1.
Presumably, the correct models of which no examples have been given.

On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.
Slope form gives you a clear image of the graph automatically as soon as you see the equation. In any given equation y=mx+b, m is the slope, which helps you visualize how steep the graph is and in which direction it goes (increases or decreases). b is the y-intercept, which is just a fancy term for where the graph intersects the y-axis. Using slope form helps you graph the graph way easier than using another form, such as standard form (Ax+By=C. What a mess!).
The x intercept is at (84, 0) and the y intercept is at (0, 112) and so with a line join the points together which then will form a graph for the given equation.

If you have anything that you're planning to graph, it's got to be an equation that has 'x' and 'y' in it. If you have an equation that has 'x' and 'y' in it and you're planning to graph the equation, then you've had enough elementary algebra to know how to solve the equation for 'y'. Do that first and bada bing, it'll be in slope/intercept form.

Solve the line equation for "y", to get it in slope-intercept form. You can immediately read the slope from this equation.Divide -1 by (slope of this first line) to get the slope of the second line - the one perpendicular to the given line. Write an equation for any line with this slope.
no the graph will be written in slope intercept form or y=mx+b
The equation of the line is of the form y = 3x + c where c is a constant. The point (4,9) is on the line, so substituting x=4, y=9 in the equation, 9 = 3*4 + c = 12 + c so c = -3 So the equation of the line is y = 3x - 3
