SOLUTION
Slope intercept form of equation of straight line is given as;
[tex]\begin{gathered} y=mx+c \\ where\text{ m=slope } \\ c=intercept\text{ on y-axis} \end{gathered}[/tex]
To determine the slope of y=4x+6;
[tex]The\text{ slope m}_1=4[/tex]
If two lines are parallel, their slope will be equal;
[tex]ie\text{ }m_2=4[/tex]
To find b, we must find the equation of the line;
[tex]\begin{gathered} Equation\text{ of line whe slope and a point is given is written as;} \\ slope=\frac{y-y_1}{x-x_1} \\ where,\text{ slope=4, x}_1=1\text{ and y}_1=6 \end{gathered}[/tex][tex][/tex]
