3x - 2y = 7 find the x value when y = 0 find the y value when x = 0x-intercept 3x - 2(0) = 7 3x - 0 = 7 3x = 7 find the y value when x = 0 y-intercept 3(0) - 2y = 7 0 - 2y = 7 -2y = 7
The equation 3x +2y = 120 models the number of passengers who can sit in a train car, where x is the number of adults and y is the number of children. Graph the equation.
3x + 2y = 120 find the x value when y = 0 find the y value when x = 0x-intercept 3x + 2(0) = 120 3x + 0 = 120 3x = 120 find the y value when x = 0 y-intercept 3(0) + 2y = 120 0 + 2y = 120 2y = 120
What is the domain and rangeof the function? Domain: Range: What do the x & y intercepts represent in relation to the problem?
Linear Equations Review. Find the slope and y intercept: y + x = -1.
ALGEBRA 1 CC Find Slope and x- and y-intercepts. Vocabulary The slope of a nonvertical line is the ratio of the vertical change (the rise) to the horizontal.
Slope Intercept Form Y intercept The y-intercept is the point where a line crosses the y axis. At this point the value of x is 0. To find the y-intercept,
Notes Over 4.3 Finding Intercepts Find the x-intercept of the graph of the equation. x-intercept y-intercept The x value when y is equal to 0. Place where.
AIM: Graphing Slope Intercept Form
2.1 Lines and Slopes. Example 1: Find the Slope Possibilities for a Line’s Slope.
Finding the Intercepts of a Line
Warm-Up Graph. Then find the slope. 5 minutes 1)y = 3x + 2 2) y = -2x +5.
Do Now Find the slope of the line passing through the given points. 1)( 3, – 2) and (4, 5) 2)(2, – 7) and (– 1, 4)
WRITING AN EQUATION FROM SLOPE INTERCEPT. Slope Intercept Form.
Slope-Intercept Form Page 22 10/15. Vocabulary y-Intercept: the point at which a function crosses the y-axis (0, y) x-intercept: the point at which a.
Gradient Intercept y = mx + c. Gradient of a line Graphs y = mx + c x y y intercept: where the graph cuts the Y axis Gradient: the slope (steepness) of.
Basic Functions and Their Graphs
Find the x-intercept To find the y-intercept, we must use 0 for x. Substitute x = 0 into 2x + 3y = 6 and solve for y: 2x + 3y = 6 2(0) + 3y = y.
Lines and Slopes.

Graphing Lines Test Review By Mrs. Anderson. Graph the following using slope and y-intercept Y=2x + 3 Y=3/4x – 7 Y=3/2x + 5 Y=4x.
“Friendship is born at that moment when one person says to another, ‘What! You too? I thought I was the only one.’” -C. S. Lewis Ch. 2 Notes Page 7 P7.
Slope Intercept Form. Y = mx + b m is the slope b is the y-intecept (0, b) Your equation must say “y = “ Example: Y = 3x + 8 m = 3 Y-intercept (0,8) Y.
