Forms of Linear Equations Quiz

What are the three main forms of linear equations?

• Quadratic, cubic, quartic

• Sine, cosine, tangent

• Slope-intercept, point-slope, standard

• Exponential, logarithmic, rational

• The slope

• The constant term

• The x-intercept

• The y-intercept

Which form is used when you know a point on the line and the slope?

• Standard form

• Slope-intercept form

• Quadratic form

• Point-slope form

What is the standard form of a linear equation?

How do you find the slope of a line that passes through two points?

• Multiply the y-coordinates and divide by the product of the x-coordinates

• Add the y-coordinates and divide by the sum of the x-coordinates

• Divide the difference of the y-coordinates by the product of the x-coordinates

• Subtract the y-coordinates and divide by the difference of the x-coordinates

Can you use either set of coordinates in the point-slope form of a linear equation?

• No, you must use the second set of coordinates provided

• Yes, but don't mix-and-match coordinates

• No, you must use the first set of coordinates provided

• Yes, but only if the line is horizontal

What is the correct way to write the point-slope form of a linear equation?

• Ax+By=C

• a(x-h)^2+k

• y-y1=m(x-x1)

• y=mx+b

Is it possible to convert from standard form to point-slope form directly?

• No, it's not possible

• No, you must first convert to slope-intercept form

• Yes, but only for horizontal lines

• Yes, with algebraic manipulation

Answer explanation

Algebraic manipulation involves doing opposite operations (undoing) to any equation to solve for a certain variable (often by isolation).
