2. Slope:3, y-intercept: 4 3. Slope:-2, y-intercept: -9
Write an equation of a line in slope-intercept form with the given slope and y-intercept. Then graph the equation
Slope:3, y-intercept: Slope:-2, y-intercept: -9
Slope:2/3, y-intercept: Slope:-5/8, y-intercept: -2

3. Graph each equation
y = 4x – y = 1/2x + 1
3. y = -3x + 2

4. (-3,-1), slope 2/5 4. (5,-2), slope -1/3
Write the equation of the line that passes through the given point and has the given slope
(1,2), slope (-2,-6), slope – 4
(-3,-1), slope 2/ (5,-2), slope -1/3

5. Write an equation of the line that passes through the given points
(2,-1), (5,2) (-4,3), (1,13)
(3,5), (5,6) (2,4), (7,2)

6. Write each equation in standard form
y – 3 = 5(x – 2) y – 7 = -3(x + 1)
y + 4 = ½(x – 3) y – 9 = -4/5

7. Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of each equation.
(2,5), y = x – (0,3), y = 3x + 5
(-4,-1), y = -2x – (-5,-2), y = -1/2x + 4

8. Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of each equation.
(2,4), y = 3x (-5,2), y = 1/3x + 4
(1,3), y = -2x – (3,0), y = -1/2x

9. Finding the inverse of a function
f(x) = 5/11x f(x) = 3x + 8
3. f(x) = 1/4x – f(x) = -4x – 12

10. Write an equation of a line in standard form
Write an equation of a line in slope-intercept form with the given slope and y-intercept.
Slope:3, y-intercept: Slope:-2, y-intercept: Slope:2/3, y-intercept: 3
Write an equation of a line in standard form
y – 2 = 5(x + 2) y + 6 = -3(x + 1) y + 4 = 7(x – 2)

11. Find the inverse of the following
