Answer:

-9/8

Step-by-step explanation:

To solve this you do the change in y over the change in x. so in this case it would be (-4)-(5)/(-2)-(-10). Which is -9/8 which is the slope.

Answer:

y=3x+5

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis)

Given that the slope is 3, we can plug this into y=mx+b as <em>m</em>:

y=3x+b

Now, to solve for <em>b</em>, simply plug in the given point:

-7=3(-4)+b\\-7=-12+b\\b=5

Therefore, the y-intercept is 5. Plug this back into the equation:

y=3x+5

I hope this helps!

Answer:A ratio compares two numbers or two quantities that are measured with the same unit. The ratio of a to b is written a to b,ab,ora:b. ... When a ratio is written in fraction form, the fraction should be simplified. If it is an improper fraction, we do not change it to a mixed number.
