Finding Equations of Straight Lines

What is the initial step to find the equation of a straight line passing through two points in Desmos?

• Inputting the equation y=mx+c

• Adding a table to input points

• Drawing the line manually

• Calculating the gradient

What are the two points used to demonstrate finding the equation of a straight line?

• (1, 2) and (3, 4)

• (3, 5) and (6, 9)

• (0, 0) and (5, 10)

• (2, 7) and (4, 8)

What is the standard form of the equation of a straight line?

• y = mx + c

• y = ax^2 + bx + c

• y = kx

• y = c

In Desmos, what symbol is used to approximate or model the equation of a line, rather than the standard equals sign?

• +

• -

• ~

• *

What is the approximate value of the gradient (m1) for the line passing through the given points?

• 0.975

• 1

• 1.33333

• 7
