Answer : y = -3/4x + 1
To find an equation that goes through the two points provided, you have to find the slope using those same two points.
The equation for slope is (y2-y1)-(x2-x1).
The slope is -3/4.
The y-intercept is already given to you in the point (0,1).
Just plug everything into an equation and you get y = -3/4x + 1.
