What is the equation of this line?
_{(in the form y = mx + c)}

• y = -3x + 2
• y = 2x - 3
• y = 2x + 3
• y = -2x - 3

A straight line has the equation −15𝑥+3𝑦−12=0. What is the slope (gradient) of the line?

Find the slope (gradient) of the line −2𝑥+3𝑦−2=0 and the 𝑦-intercept of this line.

Determine, the equation of the line which has a slope of 8 and a 𝑦-intercept of −4.

• 𝑦 = 𝑥 − 4

• 𝑦 = 8𝑥 + 4

• 𝑦 = 8𝑥 − 4

• 𝑦 = −4𝑥 − 8

• 𝑦 = −4𝑥 + 8

Determine the equation of the line passing through 𝐴(0,16) and 𝐵(1,−9)

• 𝑦 = −25𝑥 − 16

• 𝑦 = 𝑥 − 25

• 𝑦 = 16𝑥 + 25

• 𝑦 = 16𝑥 − 25

• 𝑦 = −25𝑥 + 16
