VN: 2.3 Standard Form of a Line

What is the standard form of a line equation?

• y - y1 = m(x - x1)

• y = mx + b

• ax + by = c

• a^2 + b^2 = c^2

How do you find the x-intercept of a line in standard form?

• Set y to zero and solve for x

• Set x to zero and solve for y

• Set both x and y to zero

• Multiply the coefficients

What must be true about the 'a' value in the standard form equation?

• It must be a fraction

• It must be negative

• It must be positive

• It must be zero

Are you enjoying the video lesson?

• Yes

• No

How do you convert a slope-intercept form equation to standard form?

• Subtract y from both sides

• Divide by the coefficient of x

• Multiply by the denominator to clear fractions

• Add fractions to both sides

In a real-world problem, if only adults attend an event, what does the x-intercept represent?

• The number of student tickets sold

• The total cost of tickets

• The number of tickets left

• The maximum number of adult tickets sold
