Question

Write an equation of the line with a slope of −7 and y-intercept of 1.​

Answer 1

y = -7x - 1 is the desired equation.

Explanation:

Choose the form of the equation of a straight line that requires the least amount of work. In this particular case we are given the slope (-7) and the y-intercept (1), and so use the slope-intercept form y = mx + b:

y = -7x - 1 is the desired equation.

Answer 2

y = -7x + 1

Explanation:

Remember the formula for slope-intercept form: y = mx+ b

m is equal to the slope value

b is equal to the y-intercept value

Meaning, when you substitute the values in, you get:

y = -7x + 1
