find the slope soooo its (y2-y1/x2-x1)= -4/4 so -1 is slope equation is y=-x+4

You have to find the slope using the slope formula: [latex] frac{y_2-y_1}{x_2-x_1} [/latex] [latex]( x_{1} ,y_{1} ) = (4, 0)[/latex] [latex] ( x_{2}, y_{2}) = (0, 4) [/latex] [latex]frac{y_2-y_1}{x_2-x_1} = frac{4-0}{0-4} = frac{4}{-4} = frac{1}{-1} [/latex] = -1 = m After finding slope, you have to find the equation using the point slope formula: [latex](y - y_1) = m(x - x_1)[/latex] [latex](y - 0) = -1(x - 4)[/latex] [latex]y = -x + 4[/latex] Hence, the equation is y = -x + 4 .
