Answer:
y=3x goes with m=3, b=0
y=7 goes with m=0, b=7
y=-3x+4 goes with m=-3, b=4
y=1.5x-7 goes with m=1.5, b=-7
y=-1.5x-4 goes with m=-1.5, b=-4
Step-by-step explanation:
The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.
The equation y=3x matches with m=3,b=0, y=7 matches with m=0 b=7, y=-3x+4 matches with m=-3, b=4, y=1.5x-7 matches with m=1.5,b=-7,
y=-1.5x-4 matches with m=-1.5 and b=-4.
Equation is relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. Standard form of equation is y=mx+c in which m is slope of line whose equation is taken, c is y intercept.
Slope of a line is the difference between y values divided by difference between x values. Y intercepts is a point where the line touches the y axis means here x=0.
1)y=3x
If we compare it with standard form of y= mx+c we can find that slope is 3 and y intercept is 0.
2)y=7
If we compare it with standard form then we can find that slope=0 then y intercept is 7.
3) y=-3x+4
If we compare it with standard form then we can find that slope=-3 then y intercept is 4.
4) y=1.5x-7
If we compare it with standard form then we can find that slope=1.5 then y intercept is -7.
5) y=-1.5x-4
If we compare it with standard form then we can find that slope=-1.5 then y intercept is -4.
Hence the equation y=3x matches with m=3,b=0, y=7 matches with m=0 b=7, y=-3x+4 matches with m=-3, b=4, y=1.5x-7 matches with m=1.5,b=-7,
y=-1.5x-4 matches with m=-1.5 and b=-4.
