What is the point-slope form of a line that has a slope of 3 and passes through point (1, 4)?     ​

Answers

Answer:

y-3x=1

Step-by-step explanation:

Let a point be P with coordinates (x,y)

Equation of point slope :y-y1=m(slope)*(x-x1)

y1=4,x1=1

Substituting values of x1 and y1 in the equation

y-4=3(x-1)

y-4=3x-3

y-3x=1

The equation is y-3x=1

Answer:

y-4=3(x-1)

A line has a slope of -1/2 and a y-intercept of -2.What is the x-intercept of the line?

A.-4
B.-1
C.1
D.4

Answers

Answer:  A. -4

Step-by-step explanation:

From the y-intercept, normally you follow the slope -1/2 down 1 and 2 to the right. BUT since the y- intercept here is Negative 2, you have to do the opposite to get to the x-axis.

So starting at the y-intercept -2, go UP 1, Then LEFT 2, twice. The line will intercept the x-axis at -4.
