Question

Use the image to answer the question.

An illustration of a coordinate plane with four quadrants shows the x axis extending from negative 10 to 10 in increments of 1 and the y axis extending from negative 5 to 15 in increments of 1. A solid line and a dotted line with arrows at both ends intersect each other. The equation of the solid line is y equals one half x plus 6. The equation of the dotted line is y equals 2 x plus 3. The lines intersect at left parenthesis 2 comma 7 right parenthesis which is not plotted as a point.

Estimate the solution to the system of these linear equations based on the graph.

y=2x+3

y=12x+6

Answer 1

Solve by setting equal: 2x + 3 = (1/2)x + 6 → (3/2)x = 3 → x = 2, and y = 2(2) + 3 = 7.
