Question

Consider a graph for the equation y= -3x+4. What is the y intercept?

A) 4
B) -4
C) 3
D) -3

Answer 1

A

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 4 is in this form

with y- intercept c = 4 → A

Answer 2

Choice A is correct answer.

Explanation:

y = mx+b is slope-intercept for equation of a line where m denotes slope and b denotes y-intercept of a line.

Slope is defined as the steepness of the line and it is denoted by m.

y-intercept is the point where the value of x is zero and it is denoted by any small letter.

Given equation is :

y = -3x+4

comparing above equation with general slope - intercept form , we get

m = -3 and b = 4

hence,y-intercept is 4.
