Question

A pair of linear equations is shown below:
y = -2x + 3
y = -4x - 1

Which of the following statements best explains the steps to solve the pair of equations graphically?

Answer 1

Graph the first equation, which has slope = 3 and y-intercept = -2, graph the second equation which has slope = -1 and y-intercept = -4, and find the point of intersection of the two lines.

Answer 3

Step 1 - identify which of the following slopes could be even considered right.

Remember the equation of a line is

y = mx + b

m = slope

b = y-intercept

We try to avoid giving out answers, which I'm guessing is why you're not replying. I have given you everything that you need to solve this problem.

Answer 7

no sorry i was eating got distracted

Answer 8

but i still dont understand

Answer 9

The equation of a line can be loosely written as the following -

y = mx +b

m = slope.

So, let's look through the first given equation; y = -2x + 3

Can you identify the slope?
