It would be, t= 10w + 25 And to make a graph but in values for w; w: 1 / 2 / 3 / 4 t: 35/ 45 / 55 / 65 And then you plot the points on the graph.

Determine the slope and y -intercept for each line shown. Then write the equation of the line (will give Brainliest)
Pavlova-9 [17]

Answer:

1.

y=\frac{1}{4}x+2

m= \frac{1}{4}

b= 2

2.

y=-\frac{1}{3}x+1

m= -\frac{1}{3}

b= 1

3.

y=3x+4

m= 3

b=4

Step-by-step explanation:

1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.

The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that y=\frac{1}{4}x+2

2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.

The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that    y=-\frac{1}{3}x+1

3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.

The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that  y=3x+4
