Q. Solve this system of equations by graphing. First graph the equations, and then type the solution. y=21x−3y=−23x+1
Graphing First Equation: Graph the first equation y=21x−3.- Slope(m)=21, y-intercept (b)=−3.- Plot the y-intercept (0,−3).- Use the slope to find another point: rise 1, run 2. Point (2,−2).- Draw the line through these points.
Graphing Second Equation: Graph the second equation y=−23x+1.- Slope (m)=−23, y-intercept (b)=1.- Plot the y-intercept (0,1).- Use the slope to find another point: fall 3, run 2. Point (2,−2).- Draw the line through these points.
Finding Intersection: Find the intersection of the two lines. - Both lines intersect at point (2,−2).
