Transcript of Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.

Page 1: 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

Page 3: Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.

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

Page 4: Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.

Systems of equations Graph both lines carefully Find where they intersect Write the coordinates of where they

intersect as an ordered pair

Page 5: Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.

Solve by graphingy = 1/2 x + 3

y = -2x - 2{{y = 4 x - 3

y = -x + 5

Page 6: Starter Write an equation for a line that goes through point (-3,3) and (0,3) y = 1/2 x + 3/2.

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
