hello
from the question given we have the value of slope given as 7/2 and intercept as -4
from the standard equation of line
[tex]\begin{gathered} y=mx+c \\ m=\text{slope} \\ c=\text{intercept} \end{gathered}[/tex]we can simply insert the values into the equation to solve it
[tex]\begin{gathered} y=mx+c \\ y=\frac{7}{2}x-4 \end{gathered}[/tex]the equation of the straight line is given as y = 7/2x -4
[tex]y=\frac{7}{2}x-4[/tex]
