Question

Pls help me with these 2 math question will mark brainiest.

Answer 1

Answer:

3) B

4) A

Step-by-step explanation:

3)

Formula: $y = mx + b$

Slope: $\frac{-3 - 1}{-4 - (-2)} =2$

Next, I substituted the numbers from both the chart and the slope.

$y=2x+b$

$(x, y) --> (1, 7)$

$\\7=2(1)+b$

$7=2+b$

$b=5$

Your final equation should be, $y=2x+5$.

4)

From the graph you can see (0, 4) is the y-intercept and the spaces are moving up twice and once to the right, making the slope 2.

Your answer should be, $y=2x+4$.

Answer 2

I’m not sure what the first one is, but number 4 is A) y=2x+4
