I can only give the equation right now, sorry.

y= -6x + 7

Answer:

y = -6x + 7

Explanation:

Slope-intercept form: y = mx + b

where:

  • m is the slope
  • b is the y-intercept (when x = 0)

Given: a line with a slope of -6, and y-intercept of 7

Equation: y = -6x + 7

  • y-intercept: (0, 7)

Randomly select x-values that will help you graph the equation:

when x = -2:

y = -6(-2) + 7 [multiply]

y = 12 + 7 [add]

y = 19

coordinate: (-2, 19)

when x = 1:

y = -6(1) + 7 [multiply]

y = -6 + 7 [add]

y = 1

coordinate: (1, 1)

when x = 2:

y = -6(2) + 7 [multiply]

y = -12 + 7 [add]

y = -5

coordinate: (2, -5)

These coordinates fall on the line for the linear equation. Graph them on a coordinate plane, and they should give you the line for the equation.
