What is the equation of a line with a slope of 7 and a point (1, 8) on the line?

Express the equation in the form of y=mx+b, where m is the slope and b is the y-intercept.


Enter your answer in the box.

Respuesta :

in linear function y=mx+b m represents slope so m=7. Our equation becomes y=7x+b we find b by inputting 1 for x and 8 for u to get:
8=7×1+b
now we get b=8-7=1
hence our equation is of this form:
y=7x+1
