Answer: y = 4x-23
Step-by-step explanation: I'm assuming the question asks: "A line passes through the point (4, - 7) and has a slope of 4." I had difficulty understanding the format of the question. Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We can start with y = 4x + b, since we are given the slope. We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.
y = 4x + b
-7 = 4(4) + b
-7 = 16 + b
b = - 23
The equation is y = 4x-23
