Transcript of Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.
StarterWrite an equation for a line that goes through
point (-3,3) and (0,3)
y = 1/2 x + 3/2
Algebra IIChapter 3 Section 1Graph a system of equations
Before the system of equations graph you
Graphing a line Find a point on the line and plot it
the y-intercept works well Find the slope
go up the numerator over the denominator and plot another point
Connect the dots
Systems of equations Graph both lines carefully Find where they intersect Write the coordinates of where they
intersect as an ordered pair
Solve by graphingy = 1/2 x + 3
y = -2x - 2{{y = 4 x - 3
y = -x + 5
Check
substitute the x value of the point in for the x of both equations
solve for y If the y = the y value of the point
then your solution is correct
