Answer:
The answer is y = 4x - 10.
Step-by-step explanation:
Given that the linear equation is y = mx + b where m represents gradient and b is the y-intercept. The question has given the gradient, m = 4, so we can substitute any coordinates into the equation :
[tex]y = 4x + b[/tex]
[tex]let \: x = 3 \: and \: y = 2[/tex]
[tex]2 = 4(3) + b[/tex]
[tex]2 = 12 + b[/tex]
[tex]b = 2 - 12[/tex]
[tex]b = - 10[/tex]
