Answer:

Step-by-step explanation:

To find the equation of the line in slope-intercept form we to find the y-intercept(b) and the slope(m)

For the y-intercept(b) we can see that the line crosses/intersects the y-axis at 40 so the value of b equals 40 which means our y-intercept is 40

now all that is remaining is the value of m which we can find through the formula:

m=\frac{y_2-y_1}{x_2-x_1}

we take any two coordinates which lie on the line for example

(0 , 40) and (2 , 140) and plug it into our formula

m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{140-40}{2-0}\\\\m=\frac{100}{2} \\\\m=50

so the slope of the line is 50 which is m , so the equation of the line in slope-intercept form would be:

y=mx+b\\y=50x+40

In-s [12.5K]

Answer:

In order to subtract fractions, there must be a common denominator (the number on the bottom of the fraction). 7 and 3 can be multiplied to get 21 (a common factor). To get each fraction to have a denominator of 21, they can be multiplied by 3 and 7 respectively and then subtracted. Attached is an image of the problem worked out. I apologize for the messy handwriting. Hope this helps!

Mr. Jones wants to buy 6 tickets to a play. Each ticket costs $10. Mr. Jones has $45 in his pocket.
lawyer [7]

Answer:

He needs $15 more

Step-by-step explanation:

since each ticket costs $10 dollars, and there is 6 tickets, we need to multiply 10 x 6 to get the total cost of all tickets

10 x 6 = $60

To find how much more money he needs to buy all tickets, we need to subtract $45 from the total cost of tickets, which is $60

$60 - $45 = $15

Hope you understand this explanation!
