The graph of the equation y = - 2x+5 will intersect the y-axis when y equals what value

The y value would be 5. Because in y=mx+b the b is the y-intercept

Graphs like these (lines) come in the form y = mx + b where m is the slope and b is the y intercept. Y intercept is where the graph intersects the y axis so the value would be 5
