Question

Hey! guys i need help in my retricecan you please help me?

This is true or false

1. the function h(x) equals to -6x+8 is a linear function

2. the graph of y=4x-3 passes through (1,1)

3. the x intercept of 3x+2y=9 is (3,0).

4. the y intercept of 4x-3y=12 is (0,4)

5. the slope of the line y=one half x+3 is 3.

6. if f (x)=2x+1, then f exponent one(x)=onehalfx-onehalf

*please guys help.

Answer 1

1 for an equation to be linear ,the power of the variables(x,y..) should be only 1

2.to check a point if it passes through given line,just put the coordinates of the point in the LHS and RHS given equation ,if LHS=RHS then the line passes through the point

3 for finding x-intercept ,just put yalue of y=0 in the given equation and calculate x.

4.same for y-intercept, put x=0 and get y.

5.slope m \[y=mx+c\]

6. i cant get 6th lol
