Q. NOTES \& LESSON:GrammerCelebrating Texas -...Question 11*The graph of a linear function is shown on the grid.Which equation is best represented by this graph?A y+2=57(x+7)B y−2=57(x−7)c y+2=75(x+7)D y−2=75(x−7)A
Identify y-intercept: Identify the y-intercept from the graph. The line crosses the y-axis at (0,−2).
Determine slope: Determine the slope by finding the change in y over the change in x between two clear points on the line. Using points (0,−2) and (5,5), the slope (m) is calculated as m=5−05−(−2)=57.
Formulate equation: Formulate the equation of the line using the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept. Plugging in the values, y=57x−2.
Compare with options: Compare the formulated equation with the given options. The correct equation must match the slope and y-intercept identified. Option A, y+2=57(x+7), rearranges to y=57x−2, which matches our equation.
