1.3 Enrichment and Extension
Modeling with Linear Functions
In Exercises 1-4, write a linear equation in slope-intercept form.
1. a line that passes through the points (-1, 4) and (1,4)
2. a line whose x-intercept is 3 and y-intercept is -2
3. a line that has a slope of 0 and passes through the point (2,7)
4. a line that has the same slope as 6y + 10 = 3x and the same y-intercept
as 4x - 3y = 9
In Exercises 5-10, find the value of A that would make the statement true.
y=mx+b
