100

The independent variable depends on the dependent variable.

False: the dependent variable depends on the independent
100

Write an equation if the coefficient is 4 and the y-intercept is 7.

y = 4x + 7  or  y = 7 + 4x
100
Solve for y, when x=-6 :


y=2x + 4

y= -8
100
What is coefficient?
It is the number that multiplies the variable in an equation. (shown as m in y=mx+b) also known as slope.
200

Linear relationships can be represented in only graphs.

False: They are also shown in tables and equations
200

Write an equation if the slope is -2 and the y-intercept is 4.

y = -2x + 4  or  y = 4 + -2x
200

Solve for y, when x=-7 :


y=-4x - 2

y = 26
200
What is the y-intercept?
It is where the line crosses the y-axis, when x=0.
300

Linear graphs always have a positive slope.

False: They can have a negative slope too
300

Write an equation if the y-intercept is 3 and the slope is 2.

y = 2x + 3   or   y = 3 + 2x
300

Solve for y, when x= 7:


y=52 + 3x

y = 73
300
What is an ordered pair?
A point on a coordinate plane (x,y)
400

The equation, y=mx+b represents a linear relationship.

True
400

Write an equation if the y-intercept is -2 and the slope is -6.

y = -6x - 2  or  y = -2 - 6x
400

Solve for y, when x= 0:


y= -12 + 3x

y = -12
400
What is solution of an equation?

 a number/value that, when substituted for the variable, makes the equation true.

500

The coefficient is represented by m.

True
500

Write an equation if the y-intercept is -3 and the slope is -1.

y = -x - 3  or  y = -1x - 3
500

Solve for y, when x= -5:



y= 41 - 7x

y = 76
500
What is the x-intercept?
It is where the line crosses the x-axis, when y=0.
