Answer:

number of math problems = 26

number of science problem = 16

Step-by-step explanation:

a total of 42 math and science problems for homework

Let m be the number of math problems and 's' be the number of science problems

m+s=42

You have 10 more math problems than science problems

m=s+10

substitute s+10 for m in the first equation

m+s=42

s+10+s=42

2s+10=42

subtract 10 from both sides

2s = 32

divide both sides by 2

s= 16

m=s+10

m=16+10

m=26

number of math problems = 26

number of science problem = 16

What is the equation of the graphed line in point-slope form?
Flura [38]
We first need to find the gradient of the line
\frac{y_{2}- y_{1} } {x_{2}-x_{1} } = \frac{-3-1}{-3-3}= \frac{-4}{-6}= \frac{2}{3}

From the graph, we see the graph intercepts y-axis at -1

Hence, the equation of the line is y= \frac{2}{3}x-1
