Write the equation in slopeintercept form of the line that has a slope of 3 and contains the point 2 5?
y=mx+b y0=mx0+b 5=3*2+b b=5-5=0 y=3x+0
When does the equation of a line in slope-intercept form look just like its equation in point-slope form?
When it is a line through the origin.
Given the equation of a line how is the slope calculated?
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
What is a factored form of a line equation?
when it is in its most reduced form.
What is an equation of the form ymx for the line that passes through the origin and has slope 2?
The straight line equation is: y = 2x
Write the equation in slopeintercept form of the line that has a slope of 2 and contains the point 3 7?
y = 2x + 1.
Write the equation in slopeintercept form of the line that has a slope of 3 and contains the point 4 9?
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
Write the equation in slopeintercept form of the line that has a slope of 3 and contains the point 2 5?
y=mx+b y0=mx0+b 5=3*2+b b=5-5=0 y=3x+0
Equation of line?
There are several equations; sometimes one can be more appropriate, sometimes another, depending on what data is given. For example, an equation solved for "y", i.e. of the form y = mx + b directly shows you the line's slope (which is "m") and the y-intercept (which is "b"). On the other hand, a general form of an equation of a line is ax + by = c This form is able to represent vertical lines, which can't be expressed with the slope-intercept form. There are several other equations for a line as well.
What is the general form for a line equation?
General form for a line equation is: y=mx+b.

What is the form of an equation for a horizontal line?
For a horizontal line, it is y= a value
If the equation of a line passes through the points (1, 3) and (0, 0), which form would be used to write the equation of the line?
Slope-intercept form
What is an example of the equation of a horizontal line?
A horizontal line would be of the form y= (a number). There should be no 'x's involved in the equation.
What is an equation of the form ymx for the line that passes through the origin and has slope 2?
The straight line equation is: y = 2x
