Today’s Objective To be able to find the x and y intercepts of an equation and use them to draw a quick graph.
The intercepts are where the line crosses the axis.Y-Intercept =(0,6) Y X-Intercept =(2,0) X
Finding the intercepts3x + y = 6 To find the x-intercept, let y = 0 3x + (0) = 6 3x = 6 x = 2 (2,0)
Finding the intercepts3x + y = 6 To find the y-intercept, let x = 0 3(0) + y = 6 y = (0,6)
The graph of 3x + y = 6 Y y-intercept =(0, 6) x-intercept =( 2,0) X
Compare the 2 graphs
Finding the interceptsx + 5y = 10 To find the x-intercept, let y = 0 x + 5(0) = 10 x = (10,0)
Finding the interceptsx + 5y = 10 To find the y-intercept, let x = 0 0 + 5y = 10 5y = 10 y = 2 (0,2)
The graph of x + 5y = 10 Y y-intercept = (0,2) x-intercept = (10,0) X
Find the intercepts and graph3x + 4y = 12
Finding the x-intercept3x + 4y = 12 3x + 4(0) = 12 3x + 0 = 12 3x = 12 x = 4 (4,0)
Finding the y-intercept3x + 4y = 12 3(0) + 4y = 12 0 + 4y = 12 4y = 12 y = (0,3)
The graph of 3x + 4y = 12 Y y-intercept =(0, 3) x-intercept = (4,0) X
Find the intercepts and graphy = 4x - 4 You try this one.
Finding the x-intercepty = 4x - 4 0 = 4x - 4 0 + 4 = 4x 4 = 4x 1 = x (1,0)
Finding the y-intercepty = 4x - 4 y = 4(0) - 4 y = -4 (0,4)
The graph of y = 4x - 4 Y x-intercept = (1,0) X y-intercept = (0,-4)
Warm-up Make a T-Table and graph the equation y = 2x + 2 x y
Writing an Equation of a Line
Equation of a line y = m x + b
STRAIGHT LINE GRAPHS y = mx + c.
X and Y Intercepts.
Warm Up Tuesday 11/9/10 We will graph linear equations using intercepts. Simplify each expression:
Graphing Using Tables (continued)
Ax + By = C Form: x- and y- intercepts
Y – Intercept of a Line The y – intercept of a line is the point where the line intersects or “cuts through” the y – axis.
X-and Y-intercepts. Standard Form (of a linear equation) ax + by = c, where a, b, and c are integers.
Warm up Graph the equation of the line using slope & y-intercept
Today we will graph linear equations in slope intercept form.
Quick graphs using Intercepts 4.3 Objective 1 – Find the intercepts of the graph of a linear equation Objective 2 – Use intercepts to make a quick graph.

Graph linear functions EXAMPLE 1 Graph the equation. Compare the graph with the graph of y = x. a.a. y = 2x b.b. y = x + 3 SOLUTION a.a. The graphs of.
Use intercepts to graph an equation
Example 1 Find the intercepts of the graph of. Finding Intercepts 2 1 y = x – = x – = x 10 = x STEP 1 Let 0 and solve for x to find the.
Practice Slope Intercept Form:
X AND Y INTERCEPTS. INTERCEPT In a function, an intercept is the point at which the graph of the line crosses an axis. If it crosses the y-axis it.
